Abstract :
The performance of printed element and stacked waveguide frequency selective surfaces (FSSs) are compared in the range 80-200 GHz. The angular dependence of the transmission response of each is established using simulation techniques and measurements. It is shown that printed element FSSs are less sensitive to the angle of incidence when used as flat plate diplexers.
