Abstract:
We present a novel method to reduce the mutual coupling of a Microstrip patch antenna array by using modified split ring resonator (MSRR) Metamaterial structure in this paper. The designed MSRR unit-cell consists of two nested rings, and each ring has two symmetrical splits. The original Microstrip patch antenna is operated at 2.4 GHz, and edge-to-edge distance between the original antenna elements is 31.5 mm which is about 0.25λ0. By placing MSRR Metamaterial structure to the right side radiating patch of the antenna array, the isolation of the antenna array is greatly enhanced. The simulation results show that the isolation is reduced more than 12 dB without affecting the operating frequency and radiation characteristics. The performance of the proposed MSRR loaded antenna array has been evaluated using numerical simulation in ANSYS HFSS and may be used for ISM band application.
