摘要

AbstractThe performance of a four‐frequency‐band (S/X/Ku/Ka) frequency‐selective surface (FSS) with double‐ring elements is evaluated both for a flat panel development and for a curved subreflector in a dual reflector antenna. Good agreement is observed between the measured and computed data for the flat panel FSS. To accurately predict the FSS effects on a dual reflector antenna's radiation pattern, we take into account the FSS subreflector's transmitted/reflected field variation as functions of the polarization and incident angles with respect to the local coordinates. An FSS transmission/reflection coefficient table is computed for TE and TM polarizations at various incident angles based on the planar FSS model. Next, the hybrid geometric optics (GO) and physical optics (PO) technique is implemented with linear interpolation of the FSS table to efficiencly determine the FSS effects in a dual reflector antenna. © 1993 John Wileys
