Abstract

This paper presents a high-performance circularly polarized (CP) magneto-electric (ME) dipole antenna optimized for wideband millimeter-wave (mm-wave) frequencies, specifically targeting advancements in 5G and 6G technologies. The CP antenna is excited through a transverse slot in a printed ridge gap waveguide (PRGW), which operates in a quasi-transverse electromagnetic (Q-TEM) mode. Fabricated on Rogers RT 3003 substrate, selected for its low-loss and cost-effective properties at high frequencies, the design significantly enhances both impedance and axial ratio (AR) bandwidths. The antenna achieves an impressive impedance bandwidth of 31% (25.24-34.50 GHz) and an AR bandwidth of 24.9% (26.40-33.91 GHz), with a peak gain of up to 8.4 dBic, demonstrating a high cross-polarization level. The experimental results validate the high-performance characteristics of the antenna, making it a robust candidate for next-generation wireless communication systems requiring CP capabilities.

摘要

本文提出了一种针对宽带毫米波频率优化的高性能圆极化磁电偶极天线，特别针对5G和6G技术的进步。该圆极化天线通过印刷脊形缝隙波导（PRGW）中的横向缝隙激励，其工作在准横向电磁（Q-TEM）模式。该设计基于罗杰斯RT 3003基板制造，因其在高频下具有低损耗和成本效益的特性而被选用，显著提高了阻抗和轴比（AR）带宽。该天线实现了令人印象深刻的31%（25.24 - 34.50 GHz）的阻抗带宽和24.9%（26.40 - 33.91 GHz）的AR带宽，峰值增益高达8.4 dBic，展示了高交叉极化水平。实验结果验证了该天线的高性能特性，使其成为下一代需要圆极化能力的无线通信系统的有力候选者。
