24 GHz圆波导TE01模式定向耦合器设计
Design of 24 GHz Circular Waveguide TE01 Mode Directional Coupler
摘要
Abstract
A circular waveguide TE01 mode directional coupler for high-power millimeter wave transmission is investigated.In order to reduce the size,the primary and secondary waveguides of the coupler are connected through two coupling holes in an orthogonal manner.A K-band TE01 mode circular waveguide directional coupler is designed,in which non-standard waveguides are used as secondary waveguides to improve device performance.The structural parameters of the coupler are optimized through electromagnetic simulation,and the simulation re-sults are in good agreement with the theoretical expectations.The coupler achieves a directionality of 40 dB at 24 GHz,with a more than 1 GHz directional bandwidth over a range of 20 dB.Meanwhile,the circular waveguide TE01 mode maintains good transmission efficiency and purity in this compact high-order mode directional coupler.关键词
