摘要

针对卫星工程中的无法兰波导应用需求

基于间隙波导技术

提出新型的小型化可插拔式无法兰波导连接结构及设计方法。在波导A末端的外壁四周构建周期性的金属钉床结构

波导B末端设计相应的中空屏蔽腔

将波导A插入波导B中

以间隙配合形式构成插拔式连接结构。在特定的尺寸条件下

插拔连接部位形成具有宽电磁禁带的电磁带隙结构

阻止电磁场从插拔接触面间的微小空气间隙泄露

保证了波导间正常的电磁传输性能。对两种Ku频段标准WR75波导的无法兰波导样件进行了验证

分析了加工误差及装配误差容差特性。在WR75波导工作频率9.84～15 GHz范围内

样件实测插入损耗小于0.06 dB

回波损耗分别优于30 dB和20 dB。相比WR75标准法兰连接

无法兰波导连接截面尺寸分别缩减60%和70%以上

大幅降低了传统法兰连接的体积

同时实现了波导间快速、灵活的插拔式连接

且具有良好的制造装配容差性能

可广泛应用于各种微波部件及系统中。

Abstract

To reduce the size of traditional waveguide flange in satellite systems

a novel solution to flangeless waveguide connection is proposed using gap waveguide technology. Bed of nails is arranged surrounding the outer surface of a waveguide

called part A. Part B is another waveguide with stepped transition to an enlarged end acting as the shielding cavity. Part A is inserted into part B

and a pluggable waveguide connection is constructed in the form of clearance fit. A contactless EBG structure is formed in the pluggable part under proper size conditions

and the EM wave leakage from the tiny air gap between contact surfaces is suppressed by EBG’s stop band

achieving a good EM transmission performance between two waveguides. Two kinds of Ku band prototype of the flangeless waveguide are designed and measured. Over the frequency range from 9.84 GHz to 15 GHz

the measured insertion loss of the two prototypes is less than 0.06 dB

and the return loss is better than 30 dB and 20 dB respectively. Compared with traditional WR75 waveguide flanges

the sectional size of the two prototypes decreases by more than 60% and 70%

respectively. The proposed flangeless waveguide has compact size and good error tolerance performance in manufacturing and assembling

and is easy to use

which is conductive to making fast and flexible waveguide connection without connecting screws and can be widely used in various kinds of microwave components and systems.
