Abstract: In this paper two element microstrip antenna array with dumbbell shaped defected ground structure (DGS) is on reduction of mutual coupling is presented. The proposed of DGS antenna is simulated by an soft HFSS simulation software. this work is obtain a miniaturized microstrip patch antenna array using DGS for S Band is 2.2GHz.Initally the patch antenna array is designed at C band resonates at 5.2 GHz and the proposed of DGS is integrated in the ground plane of patch antenna for size reduction and this miniaturization is at cost of gain antenna and in order to improve the gain of miniaturized radiator. Patch radiator is further modified to radiation properties, so finally the resonance frequency of an initial microstrip antenna array shifts to 3.75 GHz to 7.15 GHz with the gain of 2.92 dB and its miniaturization performance is up to 63% and its conventional microstrip is successfully accomplished. The prototype antenna is fabricated with the FR-4 substrate and this technique is validate experimentally and measured results with good agreement as stimulated results.
