| description | This work focuses on a compact circularly polarized wideband rectangular dielectric resonator antenna (RDRA) for X-band wireless applications. The wideband response of the RDRA is initially generated by a coaxial probe, a compact RDR, an air gap in the DR and a slot of rectangular shape in the ground. The circular polarization is achieved via incorporation of a unique feeding mechanism. The edge feeding of the RDRA with a coaxial probe generates the orthogonal modes in RDRA that make the design polarized circularly. The axial ratio performance is improved by adding a copper strip on the top of the DR. To validate the simulated results, the prototype design is fabricated and measured results are noted. For −10 dB reference value, the prototype has 59.74% impedance bandwidth (8.45–14.09 GHz). For 3 dB reference value of the axial ratio, the prototype has 9.24% Circular Polarization (CP) performance (10.084–11.084 GHz). The design has 6.5 dBic peak gain and 95.5% peak efficiency. Results show that simulated results are in close agreement with the measured results. |
