Este relatório visa dar a entender qual o estado actual do desenvolvimento do projecto de construção de uma antena planar (Array Microstrip), dando uma noção de qual é actualmente a melhor solução encontrada para a resolução do problema a... more
Is presented in this paper a new Ultra Wide Band (UWB) transmitter circuit design to a small Vivaldi antenna for remote acquisition of vital signals through telemetry by microwaves. Recently, interest in research on generation and... more
Higher harmonics normally accompany the performance of bandpass ¯lers; and the miniaturized microstrip dual mode bandpass ¯lters are not an exception. The use of the conventional open stub resonator to reduce such harmonics is not a... more
A novel fractal dual-mode microstrip bandpass filter design has been introduced in an attempt to produce filters with highly miniaturized size for modern wireless applications. The filter structure has been generated based on the 3rd... more
A dual-mode slotted microstrip patch resonator is introduced in this paper for use in wireless communication applications. The slot structure, etched inside the patch resonator, is in the form of the 2nd iteration Koch fractal curve;... more
This letter presents the results of experimental study of omnidirectional circular patch antenna operating in the TM010 mode. Antenna geometrical parameters have been selected on the basis of theoretical calculations. It has been shown... more
Torna-se necessário especificar quais serão, após uma análise inicial, quais serão as características pretendidas.
This paper describes the design and simulation results of a new concept in power amplification called Syncrodyne power amplification. Here we describe the design procedure for our Series-3 power amplifier for GSM waveforms. The foundation... more
