Abstract :
A specific multiple-layer radome geometry for reducing the RCS (radar cross section) of a microstrip patch antenna is presented. The radome consists of a stacked set of lossless dielectric layers whose permittivities alternate between low and high values of in /sub r/. Choosing the layer thicknesses properly makes it possible to achieve significant RCS reduction. However, the radiation efficiency is also reduced along with the RCS, so that a tradeoff occurs.<>
