Design of an Inverted U-Shaped MIMO Patch Antenna for Dual Band Applications

Abstract: A compact design of two element Multiple Input MultipleOutput (MIMO) system is proposed using an inverted U-shaped patch antenna. The antenna is fed by a coaxial feeding technique printed on a dielectric FR-4 substrate. The proposed MIMO system offers good return loss and isolation characterstics. This two element MIMO system produces dual band of frequencies with resonating frequencies at 2.8GHz and6.4GHz,which can be used for WLAN and satellite applications. The simulation results of return loss,mutual coupling and radiation pattern are presented in this paper.
