摘要

本文提出了两种新型的缝隙波导技术。第一个转换是矩形波导到V波段的沟槽波导,在15%的带宽范围内,回波损耗优于15 dB。第二个过渡是在Ka波段的矩形波导到脊隙波导,其带宽为20%,回波损耗水平高于20 dB。这些转换的目的是作为输入端口的企业馈电网络设计在缝隙波导技术。这种技术最近被证明有利于在高增益阵列天线中合理分配能量。

Design of Broadband Gap Waveguide Transitions for Millimeter-Wave Antenna Arrays
This paper presents two novel transitions in gap-waveguide technology. The first transition, a rectangular waveguide to groove-gap waveguide in the V band, shows a return loss better than 15 dB within a 15% bandwidth. The second transition, a rectangular waveguide to ridge-gap waveguide in the Ka band, exhibits 20% bandwidth with a return loss level above 20 dB. These transitions are aimed to serve as input ports in corporate feeding networks designed in gap-waveguide technology. Such technology has recently demonstrated to be advantageous to properly distribute the energy in high-gain array antennas.
