Abstract :
In this paper, an analytical method is proposed to estimate the 3dB power bandwidth of a Fabry-Pérot Cavity antenna covered by a thin frequency selective surface. The 3dB power bandwidth of the antenna is found using the broadside radiation power density of the antenna calculated based on the reciprocity theorem along with a transmission line model of the antenna and the circuit model of the FSS layer. The accuracy of the proposed method is verified by numerical simulations.
