Alibakhshikenari, Mohammad, Vittori, Marco, Colangeli, Sergio, Virdee, Bal Singh, Andújar, Aurora and Limiti, Ernesto (2017) EM Isolation Enhancement Based on Metamaterial Concept in Antenna Array System to Support Full-Duplex Application. In: Asia Pacific Microwave Conference, 13-16 November 2017, Kuala Lumpur, Malaysia.
This paper proposes EM mechanism to improve the isolation between transmitting and receiving array antennas using metamaterial EM band gap (MTM-EBG). The proposed mechanism can be applied to full-duplex array antenna system with very closely spaced arrays (0.33λo) with no degradation in radiation pattern. Using the proposed technique the isolation is shown to improve by >30 dB in an antenna array consisting of three-element microstrip patches designed to operate across 9.7 to 12.3 GHz. Parametric analysis was used to optimise the decoupling arrays performances. The proposed antenna array has physical dimensions of 65×22.5×1.6 mm3 and an electrical size of 2.16λo×0.75λo×0.053λo, where λo is free space-wavelength at mid-band of 10 GHz.
