设计了一种适合于平面阵列集成的宽带宽角覆盖毫米波微带馈电贴片天线，并进行了理论分析和实验验证。该天线在34.1 ~ 38.9GHz之间提供了13.1%的带宽，这是通过微带技术中的开槽多谐振微带贴片和匹配电路实现的。该天线采用RO 3003基片，具有顶层和接地层，与其他技术相比成本较低。对于与微带和前端电路的简单集成，馈电发生在顶层，具有微带耦合间隙馈电。宽半功率束宽（HPBW）是通过适当设计的第一谐振模式的寄生贴片来实现的。默认情况下，第二谐振模式具有宽HPBW。HPBW在匹配带宽内在100度和125度之间，这对于在接地平面上辐射的微带贴片天线是非常好的值。实测的输入阻抗和辐射特性与仿真结果吻合较好。
A novel mm-wave microstrip-fed patch antenna with broad bandwidth and wide angular coverage suitable for integration in planar arrays is designed, analyzed, and verified by measurements. The antenna provides a bandwidth of 13.1% between 34.1 and 38.9 GHz, which is achieved by a slotted multiple resonances microstrip patch and a matching circuit in microstrip technology. The antenna is built on RO3003 substrate with top and ground layers, which is low cost compared with other techniques. For simple integration with microstrip and frontend circuits, the feeding happens at the top layer with a microstrip coupling gap feed. The wide half-power beamwidth (HPBW) is achieved by suitably designed parasitic patches for the first resonant mode. The second resonant mode has a wide HPBW by default. The HPBW is between 100 degrees and 125 degrees within the matched bandwidth, which is a very good value for a microstrip patch antenna radiating over a ground plane. The measured input impedance and radiation characteristic show very good agreement with simulation results.
