Description
Summary:A three-dimensional dual-band dielectric resonator antenna, comprised of five rectangular dielectric resonator (RDR) radiating elements, is proposed for wireless communication applications. The presented multiple-input-multiple-output (MIMO)/diversity antenna system use TE<sub>1&#x03B4;1</sub><sup>Y</sup> and HEM<sub>2&#x03B4;1</sub> modes of the RDR antenna for the transmission/reception of data. The TE<sub>1&#x03B4;1</sub><sup>Y</sup> mode covers the frequency range from 3.3 to 3.8 GHz, covering Wi-MAX, sub-6 GHz, and LTE (3.41-3.5 GHz uplink/3.51-3.6 GHz downlink) 5G application bands. The HEM<sub>2&#x03B4;1</sub> mode covers Wi-Fi (5.725-5.875 GHz) and ITS 5.9 GHz (5.875-5.925 GHz) bands. The five RDR antenna elements are excited through coaxial feeds and are arranged in a cubical fashion to cover all directions, except -Z direction. The RDR elements are oriented and positioned to achieve a minimum correlation between the radiating elements. The proposed antenna exhibits a gain of 7 dB in the lower band while 7.2 dB gain is obtained in the upper band.
