A novel ferrite cross-patch antenna for RCS reduction

Abstract

This paper presents an efficient approach for the evaluation of the RCS of cross- patch antennas on ferrite substrates. The direction of the do magnetization of the ferrite is assumed arbitrarily in theta and phi. The analysis is based on a 3-D full wave analysis using method of moments. The Greens function and the excitation vector are formulated in a closed form using the transmission matrix approach. The linearly-varying basis function is used. A novel cross patch antenna is described and its performance compared with the full patch is also presented. The cross patch antenna minimizes number of RCS resonances and RCS levels.
