Abstract: An analysis of a linear array of four microstrip triangular patches modeled on LiTiMg ferrite has been carried out. Here, polycrystalline LiTiMg ferrite, which is synthesized by the solid state reaction technique (SSRT), has been used as a substrate. The comparison of radiation pattern and some other parameters when the antenna array is biased, perpendicularly with varying magnetic field, or unbiased has been presented in this paper. The results obtained are quite different in comparison to other tested ferrites like LiTi and LiTiZn. The results suggest that the proposed antenna will be useful for scanning purpose in defense systems. The electric and magnetic properties of ferrite have also been tested and presented.
