摘要

提出了一种采用低损耗双面缝隙波导(DSGWG)馈电网络的w波段磁电偶极子天线阵列，具有高增益和宽带性能。ME偶极子天线元件由一个DSGWG开槽作为等效磁偶极子辐射和一对金属引脚作为电偶极子工作组成。馈电网络采用DSGWG功率分配器，降低了传输损耗，提高了天线增益。仿真结果表明，天线单元在83 GHz ~ 115 GHz范围内的增益大于8 dBi，增益波动小于3 dB。通过重新配置ME偶极子天线元件和馈电网络，还设计了增益高达14.8 dBi的$1\ × 4$ ME天线阵列。

W-band High-Gain Magneto-Electric Dipole Antenna Array with Double-Sided Gap Waveguide Feed Network

A W-band magneto-electric (ME) dipole antenna array using a low-loss double-sided gap waveguide (DSGWG) feed network is presented with high gain and wide band performance. The ME dipole antenna element is composed of a DSGWG open slot radiating as an equivalent magnetic dipole and pairs of metallic pins working as electric dipoles. The feed network is composed of DSGWG power dividers, which could reduce transmission loss and improve antenna gain. The simulated results show that the antenna element achieves a gain over 8 dBi from 83 GHz to 115 GHz, and the gain fluctuation is below 3 dB. The $1\times 4$ ME antenna array is also designed with a gain up to 14.8 dBi by reconfiguring ME dipole antenna elements and the feed network.
