High Isolation Dual-Polarized Dielectric Resonator Antenna for MIMO LTE Applications

Abstract

In this paper high isolation dual-polarized Dielectric Resonator Antenna (DRA) for Multiple-Input Multiple-Output (MIMO) Long Term Evolution (LTE) applications is designed and fabricated. High isolation more than 50 dB is achieved through Quasi-orthogonal modes at 2.6 GHz with hybrid feeding mechanism. Port 1 and port 2 excite TEx and TEYmodes through microstrip feed line and coaxial probe, respectively. The proposed design is analyzed for distinct ground planes which demonstrate negligible effect on gain and S-parameters. Simulated and measured results reveal that the proposed design is appropriate for MIMO LTE terminals.
