A circular array of eight microstrip circular patches modeled on synthesized LiTiMg ferrite substrate has been investigated under the externally applied perpendicular DC magnetic field. LiTiMg ferrite substrate has been synthesized by the Solid State Reaction Technique (SSRT). Here, we also presented a comparison of radiation pattern and some other parameters, when the antenna array is biased and unbiased. Having LiTiMg substrate with perpendicular magnetic field, we reported a reduction of side-lobes, increased directivity and better radiation power response of array.

Abstract


A circular array of eight microstrip circular patches modeled on synthesized LiTiMg ferrite substrate has been investigated under the externally applied perpendicular DC magnetic field. LiTiMg ferrite substrate has been synthesized by the Solid State Reaction Technique (SSRT). Here, we also presented a comparison of radiation pattern and some other parameters, when the antenna array is biased and unbiased. Having LiTiMg substrate with perpendicular magnetic field, we reported a reduction of side-lobes, increased directivity and better radiation power response of array.
