Antennas play a crucial role in enabling detection within these radar systems. This article is dedicated to research efforts focused on developing a microstrip antenna design using array techniques to achieve high gain. The research methodology follows Thiagarajan's 4D approach, encompassing the Define, Design, Develop, and Disseminate stages. To optimize performance, the research encompasses the creation of various antenna designs, including single patches, 1x2, 4x4, and 8x4 arrays, employing feed and coaxial insert enumeration methods. Additionally, comparisons are drawn between two substrates, specifically FR-4 and Rogers RT-5880. Parameters under scrutiny encompass gain, VSWR, return loss, bandwidth, and radiation patterns. The design process for microstrip antennas involves intricate dimensional calculations and array method selection, followed by a detailed application-based design. The results consistently demonstrate VSWR values below 2 and return loss values below -10 dB for microstrip antenna designs on both FR-4 and Rogers RT-5880 substrates. The most significant gains were achieved by an 8 x 4 array design employing the insert feed enumeration method on a Rogers RT-5880 substrate, reaching an impressive 17,979 dBi. The widest bandwidth is observed in the design of the 1x2 array using the Rogers RT-5880 substrate, reaching 651.1 MHz. Moreover, it is evident that an increase in the number of patches in the array corresponds to an increase in gain. Notably, Rogers RT-5880 material demonstrates a superior capacity to produce higher gain compared to FR-4 substrates.

The purpose of this study was to visually observe the characteristics of the airflow on the upper surface passing through the NACA 43018 airfoil with varying angle of attack positions. The vortex profile of the generator x/c = 20% of the leading edge. Variations in this study are the angle of attack (α) and the placement of the generator vortex on the airfoil. The freestream speed used is a speed of 5 m/s, and at an angle of attack (α) of 0°, 3°, 6°, 9°, 12°, and 15°. From this study, it was found that the ratio of separation points between airfoils without VG compared to airfoils with VG and D = 10 mm at angles of attack (α) = 0°, 3°, 6°, 9°, 12°, and 15°had significant differences in separation points. Airfoil with VG and D = 20 mm at an angle of attack (α) = 0°, 3°, 6°, 9°, 12°, and 15°can delay separation better than D = 10 mm.

The use of Unmanned Aerial Vehicle (UAV) demands high aerodynamic performance because it strongly supports the cruising range and fuel or battery used. By reducing drag and increasing the lift optimally, the resulting lift to drag ratio will get maximum results. This study compares the use of winglets in UAVs at low Reynolds numbers. This is very important because generally UAVs are used at low Reynolds numbers. The freestream used is Re = 2.34 x 10 4 on several low to high angle of attack. The type of airfoil used is Eppler 562 which is equipped with a winglet. Winglets used are simple winglets, blended winglets, and wingtip fence. The geometry was analyzed using numerical simulations namely computational fluid dynamic (CFD). The turbulent model used in this study is K-ω SST on Ansys 19.1. From this study it was found that the use of a wingtip fence produced the best aerodynamic performance compared to other configurations. In addition, the use of a wingtip fence can delay stall and separation better than simple and blended winglets.

SDR is a transmitter and receiver system that uses digital signal processing to code, decode, and modulate data. GNU Radio is used as a transmitter and receiver model for quality measurements for the working of the OFDM system under various conditions. This measurement will compare real-time data transmission performance results through AWGN channels and dynamic channel models, namely Rayleigh Distributed (NLOS) and Rician (LOS). The specification of the OFDM system used in this study is to use GNU Radio software with BPSK modulation (Binary Phase Shift Keying). The simulation model's output in the GRC during real-time data transmission via AWGN and Rayleigh distributed (NLOS) and Rician Distributed (LOS) model channels with GNU Radio is the performance of OFDM signals with the noise of 25mV, 50mV, 100 mV, and 200mV. The results of the research simulation obtained SNR values on AWGN, NLOS, and LOS channels directly proportional to noise. The SNR value is down significantly to four times the initial value.

This separation will result in secondary flow which can be detrimental to airfoil performance. Until now, aircraft often use a slotted type flap that can prevent separation so that it can reduce the value of less resistance. This study will examine the performance and aerodynamic characteristics of the modified single-slotted flap on the Cessna 208b Grand Caravan wing. The method used is a numerical simulation with CFD software in the form of ANSYS. The test object is a modified Cessna 208b Grand Caravan wing with a single slotted flap with a flap angle (α F ) of 0°, 15°, and 30°to determine the effect of aerodynamic performance. The angles of attack reviewed are α = 0°, 2°, 4°, 6°, 8°, 10°, 12°, 14°, 15°, 16°, 18°, and 20°. The fluid flow used is air with a cruising speed of 96 m/s above sea level in stable conditions. The simulation results show that the addition of flap angle modification on the Cessna C208b Grand Caravan wing can affect both performance and aerodynamic characteristics. At a speed of 96 m/s, increasing the flap angle can decrease the value of C L /C D at high angles of attack. However, the addition of the flap angle can provide a better C L /C D value at low angles of attack.

With the slightly curved side of the airfoil, there is a point of separation in the airflow passing through the airfoil. In this research, aerodynamic testing is carried out, using numerical simulation with Ansys software. This study used NACA 23018 specimens which were given variations of the vortex generator and swept back wing. The type of vortex generator used is a triangular vortex generator with a length of 25 mm, and a height of 10 mm with a straight installation. The distance of the vortex generator to the leading edge is x/c = 10% and 15%, the swept angle is 15°, and the angle of attack varies. The freestream speed used is 20 m/s. Simulation results on the airfoil with the addition of a vortex generator can affect both performance and aerodynamic characteristics. The vortex generator on the airfoil can delay the airfoil separation, and can also delay the stall where the plain airfoil stalls at α = 15°with the addition of the vortex generator that has not stalled at this angle of attack. A vortex generator can affect the value of C L /C D . Overall, the most optimal variation of the vortex generator is the vortex generator with x/c = 15% where the C L /C D value is greatest at an angle of attack α = 12°which is 13.13.

The occurrence of flow separation on the part of the flow attached to the wing (boundary layer) can cause a stall. Separation of flow occurs when the angle of attack begins to increase. This can be done by adding a turbulent generator to the upper surface airfoil. A vortex generator is a type of turbulent generator that can accelerate the transition from the laminar boundary layer to the turbulent boundary layer. The method uses a tool in the form of a Wind Tunnel Open circuit. By applying smoke to the Wind Tunnel and accelerating the fan against smoke. In this experiment, the variations used are Airfoil NACA 43018, triangular type vortex generator with the straight arrangement, vortex generator distance x/c 20% from the leading edge, angle of attack (α) = 0°, 3°, 6°, 9°, 12°, and 15°, and freestream velocity speed 3 m/s. From the experimental results, this study shows that using a triangular vortex generator has been shown to improve aerodynamic performance and the performance of the NACA 43018 type airfoil. The 43018 type airfoil that uses a vortex generator compared to an airfoil that does not use a vortex generator can increase the transition from laminar flow to turbulent flow.

In this research, analysis of the aerodynamic characteristic has been done by using computational fluid dynamics (CFD). The purpose of this analysis is to find out the difference in the airflow between NACA 2412 with an additional gothic vortex generator and NACA 2412 without an additional vortex generator, and also to find out the airflow characteristic on NACA 2412 with varying angle of attack. The Research method used is analysis simulation on test object airfoil NACA 2412 with an additional gothic vortex generator with straight configuration with the angle of attack variation 0°, 2°, 4°, 6°, 8°, 10°, 12°, 15°, 16°, 17°,19°, 20°, 23°, and 25°. Space between installed vortex generator is 60 mm with the size of vortex generator length is 25 mm, height 10 mm, and installed on x/c = 10% and 15% direct to chord line from the leading edge. The result of the research shows that the additional vortex generator on NACA 2412 can delay airflow separation. In 15% additional position direct to the chord line from the leading edge has better distribution and the highest lift coefficient, so in this research, the 15% additional position direct to the chord line from the leading edge is the most effective to use.

The research method used is a simulation analysis method on the NACA 0012 test object with ANSYS-CFD software which is given a variation in the shape of a rectangle vortex generator with a length of 15 mm, a width of 10 mm, and a distance between vortex generators of 10 cm. The angles of attack reviewed are 0°, 2°, 4°, 6°, 8°, 10°, 12°, 14°, 15°, 16°, 18°, and 20°. The result of this simulation is that the presence of a rectangular vortex generator on airfoil NACA 0012 can affect both performance and aerodynamic characteristics. The vortex generator on the airfoil can delay the occurrence of separation and can delay the occurrence of stall on the NACA 0012 airfoil, where the ordinary NACA 0012 airfoil stalls at α = 14°with the addition of the vortex generator has not stalled at this point. With this, the NACA 0012 airfoil which is given a vortex generator can affect the results of C D . Overall, the most optimal variation is the NACA 0012 airfoil which is given a vortex generator with x/c = 15% where the value of C D is greatest at an angle of attack α = 18°.
