Abstract

This letter proposes a new broadband high-power octopus-format mode transducer used for Ka-band horn antennas. The mode transducer consists of two parts: a mode converter and an irregular planar power combiner. The mode converter, based on circular waveguide TE01 mode, adopts three metal posts with stepped transition and eight-way over-mode waveguides with radiating distribution. The irregular planar power combiner, based on E-plane T-junction, has eight ports uniformly distributed along the circumference. Sample processing was carried out on the mode transducer and a back-to-back testing was conducted. The minimum return loss of the input port 12 dB, the maximum loss 0.45 dB, and the lowest transfer efficiency 90.1% are realized within 25 GHz to 43 GHz with a relative operating bandwidth of 52.9%. The high power characteristics of pulse and continuous have been further confirmed through simulation and experiments.

用于喇叭天线的宽带大功率模式换能器

这封信提出了一种用于ka波段喇叭天线的新型宽带大功率章鱼格式模式换能器。模态换能器由模态变换器和不规则平面功率合成器两部分组成。模式变换器基于圆波导TE01模式，采用三根阶梯式过渡金属柱和辐射分布的八路过模波导。基于e -平面t型结的不规则平面功率合成器有8个端口沿圆周均匀分布。对模态传感器进行了样品处理，并进行了背靠背测试。在25 GHz ~ 43 GHz范围内，输入口回波损耗最小12 dB，最大损耗0.45 dB，传输效率最低90.1%，相对工作带宽为52.9%。通过仿真和实验进一步证实了脉冲和连续的高功率特性。

期刊介绍： IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
