A capacitive loaded CRLH in reversal triple band MIMO antenna

Abstract

In this paper, we present a compact and high isolated multiband two elements MIMO antenna. The single antenna is based on new capacitor loading of composite right/left handed (C-CRLH) unit cell configuration. A resonant one cell antenna is designed for having triple band at 1.95 GHz, 3.6 GHz and 6.5 GHz. The MIMO configuration has been designed in opposite mirror configuration to have high isolation between the elements without the need of using additional mutual coupling techniques between the elements. The single antenna overall size is 38 28 mm2. The achieved results confirm that the antenna has reflection coefficient less than-10 dB at the three frequencies and transmission coefficient less than-20 dB. The obtained results are achieved using circuit modeling and full wave simulations. � 2019 IEEE.
