Waveguide adjustable coupler and adjusting method thereof

The invention discloses a waveguide-adjustable coupler and an adjusting method thereof, and belongs to the field of microwaves. According to the coupler, the two back-to-back waveguide bridges are adopted, the coupling amount of the waveguide coupler can be adjusted in cooperation with the mode that the tuning screws tune the phases, the coupling amount can be continuously adjusted, and meanwhile good echo characteristics and isolation characteristics can be guaranteed; the tuning position of the tuning screw is at the empty waveguide, and the size space is large, so that the antenna can work in a millimeter wave frequency band; furthermore, the waveguide is split from the E surface, the narrow edge of the waveguide is provided with a threaded hole, and the waveguide is adjusted on the front surface of a product, thereby facilitating debugging and production and manufacturing. 本申请公开了一种波导可调耦合器及其调节方法，属于微波领域。该耦合器采用两个背对背的波导电桥，配合调谐螺钉调谐相位的方式实现波导耦合器的耦合量可调，耦合量可连续调整，同时能够保证较好的回波特性以及隔离度特性；且调谐螺钉调谐的位置在空的波导处，尺寸空间较大，因此可以工作于
