In this paper, a W-band magneto-electric (ME) dipole antenna fed by double-sided gap waveguide (DSGWG) feeding network is presented. The ME dipole antenna element is designed based on the end-fire DSGWG and extended ridge with pins. The end-fire open slot of DSGWG radiate as a magnetic dipole, and the metallic pins in extended ridge radiate as electric dipoles. Taking advantage of this DSGWG structure, the antenna element achieves with high gain and wide bandwidth performances. The antenna element is fabricated and measured with an impedance matching bandwidth of 85–110 GHz for |S₁₁| < −10 dB, and maximum realized gain of 9.2 dBi. A four-way feeding network based on the DSGWG is designed and connected directly to the ME dipole antennas. The antenna array with ease integration and fabrication properties is designed to validate the performance of antenna elements. The measured average realized gain of the antenna array reaches up to 15.3 dBi over the bandwidth of 88–110 GHz.

在本文中，提出了一种由双侧间隙波导 (DSGWG) 馈电网络馈电的 W 波段磁电 (ME) 偶极子天线。ME 偶极子天线元件基于端射 DSGWG 和带引脚的扩展脊设计。DSGWG 的端射开口槽作为磁偶极子辐射，延长脊中的金属销作为电偶极子辐射。利用这种DSGWG结构，天线元件实现了高增益和宽带宽性能。天线元件的制造和测量具有 85–110 GHz 的阻抗匹配带宽，用于 | 小号₁₁| < −10 dB，最大实现增益为 9.2 dBi。设计了一个基于 DSGWG 的四路馈电网络，并将其直接连接到 ME 偶极子天线。具有易于集成和制造特性的天线阵列旨在验证天线元件的性能。在 88-110 GHz 的带宽内，测得的天线阵列平均实现增益高达 15.3 dBi。
