Abstract

Millimete-wave (MMW) communication and sensing systems suffer from the challenge of realizing dual-polarized phased array antenna with large beam-scanning angles, due to the array unit can hardly having the radiation pattern with wide 3 dB beamwidth in both orthogonal planes (one is the beam-scanning plane). In this letter, we propose a dual-mode coupling radiation mechanism to integrate a monopole mode and a patch mode for obtaining 3 dB beamwidth larger than 120° in both two orthogonal planes. Hence, the array cascaded from the antenna unit can realize a wide beam scanning of −60°∼+60° within gain degradation of less than 3 dB in both ±45° polarizations. Based on this principle, a ±45° dual-polarized antenna unit is designed, and a prototype of a 1 × 8 ±45° dual-polarized phased array is fabricated. Experiments demonstrate that the MMW array operating in 25.5 GHz to 28 GHz (active |S₁₁|< −10 dB) can scan from −60° to +60° with gain fluctuations less than 3 dB. The proposed MMW antenna can be applied to B5G/6G MMW communications and sensing.

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.
