For the reader, a coherent frequency modulated continuous wave (FMCW) bi-static radar receiver architecture is used. A signal processing technique based on Hilbert transform is used to decode tag's data by detecting both amplitude and phase information. Accurate detection of the tag is achieved in simulations. With this interrogation technique, a very low cost chipless RFID reader with only one voltage controlled oscillator (VCO) is possible. In contrast to previous generation readers, this reader does not need any calibration tag to decode data.

These types of sensors can be used for various applications including structural health monitoring, pressure, airflow and displacement detection, temperature, humidity, partial discharge monitoring and so on. A novel concept of high resolution crack sensing using super wideband antenna is also introduced here along with a brief review on airflow and partial discharge sensors.

The tag consist of a UWB monopole antenna loaded with multiple cascaded spiral EBGs which have a 1:1 correspondence with data bits. The 4th generation tag is less sensitive to tag orientation and has smaller size than earlier generations of the tag. A proof-of-concept tag is developed and tested which has

It has been shown that the junction capacitance plays an equally important role in determining the position of attenuation pole of the unit cell DGS as the gap capacitance. Theory is validated against simulation results by commercially available MoM Solver CST design environment. Good agreements between simulated and calculated results validate the theory.
