Reconfigurable frequency selective surface for fabry-perot cavity antenna system

Abstract

This paper presents reconfigurable Fabry-Perot Cavity (FPC) antenna systems to switch one mode to other with respect to near- and far-field performance. The fluidic channel is created and integrated into the FPC system. The channel is filled with air or deionized (DI) water. The fluidic FPC systems are compared to a fixed FPC design without the fluidic housing. Simulation and measurement results are presented and discussed.
