Summary: | In this study, a novel dual-band multiple-input multiple-output (MIMO) rectangular dielectric resonator antenna (DRA) for Worldwide interoperability for microwave access (WiMAX) (3.4-3.7) GHz and wireless local area network (WLAN) (5.15-5.35) GHz applications is proposed and investigated. The design operates at fundamental TEδ11 x, TE1δ1 y and higher order TEδ21 x, TE2δ1 y modes, excited through two coaxial probes, symmetrically placed adjacent to the DRA. A compact design is achieved by stacking a high permittivity material. The obtained impedance bandwidth at 3.6 GHz is 9.97% and at 5.2 GHz is 8.88%. Measured antenna gain through both ports at 3.6 GHz is 5.7 dBi and at 5.2 GHz is 6.61 dBi, respectively. Isolation achieved at 3.6 GHz is -13 dB and at 5.2 GHz is -16 dB, respectively. Co- and cross-polarisation, radiation efficiency, diversity gain, envelope correlation and mean effective gain of the proposed design are measured. Results show that the proposed design is suitable for use in MIMO WiMAX/WLAN applications. |
