A Ka‐band power divider/combiner with dual magnetic coupling semicircular ring probes is proposed in this paper. Firstly, a broadband microstrip‐to‐waveguide transition with semicircular ring probe is designed based on the side‐inserted structure of magnetic field excitation in a rectangular waveguide. The insertion loss of the proposed transition is less than 0.7 dB in Ka‐band assisted by the dual symmetrical broadband probes and rectangular waveguide. Then, the divider/combiner is proposed using the new transition with magnetic coupling from narrow wall into the rectangular waveguide. The bandwidth of the divider/combiner is more than 9 GHz (from 27 to 36.7 GHz), and the insertion loss of the single divider/combiner is less than 3.3 dB. Finally, the performance of the proposed divider/combiner is validated through simulations and measurements. The proposed design has potential applications in microstrip circuits.

使用两个侧面插入的磁耦合半圆环形探头的Ka频段功率分配器/组合器

本文提出了一种具有双磁耦合半圆环形探头的Ka波段功率分配器/组合器。首先，基于矩形波导中磁场激励的侧插入结构，设计了带有半圆环形探头的宽带微带到波导过渡。在双对称宽带探头和矩形波导的辅助下，建议的过渡段在Ka波段的插入损耗小于0.7 dB。然后，利用从窄壁到矩形波导的磁耦合的新过渡，提出了分频器/合并器。分频器/组合器的带宽大于9 GHz（从27到36.7 GHz），并且单个分频器/组合器的插入损耗小于3.3 dB。最后，通过仿真和测量验证了所提出的除法器/合并器的性能。
