Abstract

A simple and compact rectangular microstrip antenna with circular arc defected patch surface is proposed for significant suppression of cross polarized (XP) radiation and improved polarization purity. The proposed antenna has been studied methodically with theoretical justifications. Simulation and experimental results are also presented in support of the present idea. The proposed structure is simple and easy to fabricate. Around 25 dB of XP radiation isolation from co polarized (CP) radiation is revealed. The effect of dimensions of the defect on the radiation performance of the proposed antenna has been thoroughly examined and verified. The exploration of the new structure is carried out with a view to eliminate higher order orthogonal resonance without altering its dominant mode field configuration.
