Abstract
A wideband millimeter-wave circularly polarized (CP) dielectric resonator antenna (DRA) is proposed in this letter based on substrate-integrated suspended line (SISL). To generate CP waves, a square DRA is cut off two corners. The introduction of the dielectric ring not only serves to fix the DR, but also improves the antenna matching and axial ratio bandwidth. In order to increase the axial ratio bandwidth and realized gain, a stacked strip is introduced on the C1 layer. The proposed antenna is fabricated and measured, and the measured results show the antenna has an impedance bandwidth of 27.94%, which is from 23.4 GHz to 31 GHz. The axial ratio bandwidth of 30.55% is from 23.3 GHz to 31.7 GHz, and the measured peak gain is 7.5 dBic.
期刊介绍：
IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
