A dual band hybrid mimo dielectric resonator antenna for long term evolution applications

Abstract

Dielectric resonator antennas (DRAs) are widely used in the last two decades. Comparison with microstrip patch antenna, DRA can provide high bandwidth, low metallic losses and high radiation efficiency. Smaller size of meander line is suggested to replace conventional microstrip line. Multiple-input multiple-output (MIMO) can increase more channel capacity and throughput compared to single port. In this project, a dual band MIMO hybrid DRA for LTE applications is proposed. This hybrid technique will be consisted of DRA and meander-typed antenna as radiators which can operate at LTE band 8 (880-960 MHz) at ???? = 900 MHz, LTE band 2 (1.85-1.99 GHz), 3 (1.71-1.88 GHz), and 9 (1.7499-1.7849 GHz) at ???? = 1.8 GHz respectively. A triple band is obtained in the simulations of HFSS software with additional 2.3 GHz for LTE Band 30 (2.305-2.360 GHz). The MIMO prototype has bandwidth up to 6.53 % at Port 1 and 12.68 % at Port 2, with isolation ranging - 6.10 dB to - 22.76 dB at 0.9, 1.5, 1.8 and 2.5 GHz.
