Design and research of modified split ring resonator for reduction of mutual coupling in microstrip patch antenna array

Abstract

In this document, we proved a new technique for eliminating the impact of mutual connection amongst elements in an antenna array by integrating the Metamaterial Hybrid Split Ring Resonator (HSRR). The HSRR suggested unit-cell consists of a single circular ring resonator, each rounded with two symmetrical divisions, with one hexagonal ring resonant. The insulation of over 13 dB without affecting the working frequency and radiation features shall be accomplished by integrating the HRSR metamaterial framework near the correct side of the standard radiating patsch of the antenna array running at 2.4 GHz. The efficiency of the HSRR antenna array proposed has been numerically assessed.
