A Multi Input Multi Output (MIMO) Rectangular Dielectric Resonator Antenna (RDRA) for 1.8 GHz Long Term Evolution (LTE) applications is investigated and presented. The antenna consisting of two rectangular dielectric resonator elements, both resonators are fed by microstrip feed line is etched on FR4 substrate. The simulated impedance bandwidth for port1 and port2 is 26.38% (1.6176-2.1093 GHz) and 26.80% (1.6146-2.1143GHz) respectively for |S11| ≤ -6dB, which can operate on LTE band 1-4,9,10,35-37 and 39. The gain of the MIMO RDRA is 3.2 dBi and 3.1 dBi at 1.8 GHz for port 1and port 2, respectively. The S-parameters, isolation, gain, and MIMO performance such as correlation coefficient and diversity gain of the presented RDR Antenna have been studied.

Rectangular Dielectric Resonator Antenna

In this article, a novel offset microstrip line feed Rectangular Dielectric Resonator Antenna is used for bandwidth enhancement. The parameters such as Bandwidth, Return Loss and Radiation efficiency are improved in the proposed antenna. A comparison is also shown for the proposed feed structure with and without conformal strips. The improvement in the bandwidth is observed from 25% to 65% by optimizing the antenna design parameters. It works in three frequency bands, that is, 2.03-3.69 GHz, 3.86-7.26 GHz, and 7.32-9.26 GHz. The proposed antenna is appropriate for WIMAX/WLAN applications.
