Abstract :
Radar cross sections (RCS) of rectangular, circular and triangular microstrip patch antennas are presented which are printed on LiTi ferrite substrate in X-band (8-12 GHz) region. In this paper, we precise the preparation of a polycrystalline LiTi ferrite of 2200 Gauss saturation magnetization. The comparison of RCS patterns among RPMA, CPMA and TPMA shows the affective study of radar cross section which differentiates the stealth capacity as well as miniaturization due to the ferrite substrate application.
