Abstract

In an antenna array the far field radiation pattern is affected by the mutual coupling between the array elements. This paper presents a solution to reduce the mutual coupling between two element patch antenna array by incorporating Complementary Split Ring Resonator (CSRR) metamaterial structure on the ground plane. The proposed antenna is designed consisting of two hexagonal patch elements with CSRR structure. By incorporating the CSRR structure mutual coupling has been reduced from -10dB to -24 dB. The two-element patch antenna array is fabricated and S parameters of the prototype are measured and compared with the simulation results. The measured and simulation results are in good agreement with S11<-10dB, S12<-24 dB..
