Analysis of conformal frequency selective surface radome

In this paper, the transmission characteristics of a conformal frequency selective surface (FSS) radome which is designed to operate in Ku-band is compared to its planar counterpart. The radome is designed to have narrow band-pass characteristics with a performance that is independent of the polarization and the angle of incidence of the incoming wave. The optimum dimension of the radome is optimized through the simulations of the infinite planar structure. Then, the performance of the conformal structure is analyzed by simulating the same FSS over an infinite half cylinder.
