Abstract

A practical design of reduction mutual coupling is presented between patch antenna elements by using symmetrical microstrip structures in the paper. The patch antenna design consists of the following: two antenna patches, a rectangular substrate plane, a pair of three orders symmetrical microstrips, and a common ground. By using the proposed scheme, approximately 35 dB mutual coupling reduction is achieved at central frequency of 7.3 GHz while maintaining gain of 2.3 dB and directivity of 5.53dBi. Return loss slightly decreases by 2.91 dB from −23.12 to −20.21 dB. In contrast, it exerts no effects on gain radiation characteristics in a no microstrip setup. Simulation results of this technique are verified validated using experimental measurements. [ABSTRACT FROM AUTHOR]
