Investigation of spatial filters at microwave frequencies: Application for antenna directivity enhancement

Abstract : We report the theoretical and experimental investigations of a frequency selective surface (FSS) operating in the microwave regime. Numerical simulations using finite element method and reflection-transmission microwave measurements have been performed and a good quantitative agreement has been observed. Angular robustness is also demonstrated which makes it promising in telecommunication applications. The potential application of the FSS as a partially reflecting surface (PRS) reflector Fabry-Pérot (FP) cavity is proposed and evaluated. Measured return losses and radiations patterns done in an anechoic chamber agree very well with the simulated ones. A high directivity of 20 dBi is observed for the FP cavity. © 2012 Wiley Periodicals, Inc. Microwave Opt Technol Lett 54:1327-1332, 2012
