摘要

In this article, a hybrid microstrip fed dual-cylindrical dielectric resonatorantenna (dual-CDRA) has been proposed for the sub-6 GHz band applicationwith a wide circular polarization band. The proposed hybrid microstrip feedcylindrical dielectric resonator antenna utilizes an S-shaped microstrip feedline to excite fundamental HE_(11δ) like mode and hybrid mode in dual-CDRAs.The presented antenna structures are acting as monopole antenna separatelywith 48.75% (3.88-6.38 GHz) bandwidth whereas both radiators called dual-CDRAs enhances the bandwidth up to 93.06% (2.16-5.92 GHz) in addition withan axial ratio bandwidth of 15.2% (3.52-4.1 GHz). The proposed antenna isapplicable for WiMAX (3.4-3.69 GHz), and WLAN application of 802.11d and8.02.11e IEEE standard. For validation of simulated results, an antenna prototypehas been fabricated and experimentally verified. A good agreementbetween simulation and measured results are obtained. The simulation resultshave been carried out by using Ansys HFSS 14.0 version software.
