Rectangular array of four elements of microstrip circular patches modeled on LiTiZn ferrite substrate is presented. Here we have considered LiTiZn ferrite as a substrate which has been synthesized by the solid state reaction technique (SSRT). In this paper we present a comparison of radiation pattern and other parameters when the antenna array is biased perpendicularly with varying magnetic field. The array antenna using LiTiZn with magnetic biasing, reports a reduction of radiation of side-lobes with increased directivity with better radiation power response.
Keywords. Substituted ferrite, microstrip array antenna, X-band frequency range.
