A compact high performance millimeter-wave microstrip patch antenna using metamaterial

Abstract

This paper presents, the effectiveness of the metamaterial (MTM) of the double-split ring structure and applied to an optimized antenna is for performance enhancement. The measured bandwidth is 26.29 GHz – 29.89 GHz (12.8 %) for |S11| < – 10 dB. It also achieved a high broadside gain varying from 11.60 – 13.20 dBi. This result shows that the antenna gain is increased by 7.67 dBi and bandwidth is improved up to 4.9 % compared to the patch antenna without the MTM. The proposed antenna provides a high gain and wide bandwidth, which can be used as an alternative to array antenna in the mmWave band.
