Microstrip circuit debugging method and adjusting module

The invention provides a microstrip circuit debugging method and an adjusting module. The method comprises the steps: manufacturing an adjusting module, wherein the adjusting module is a metal block with the width smaller than or equal to one fourth of the wavelength of a microwave device to be tested; assembling a microwave testing system, and placing one or more adjusting modules on a microstrip circuit; debugging: moving the adjusting module along the extension direction of the microstrip line by means of an insulating clamp, and recording the power of the microwave device measured by the microwave tester in real time; carrying out impedance matching, wherein a position corresponding to the adjusting module when the power of the microwave device is maximum is marked, and a copper strip or an indium sheet matched with the length and the width of the adjusting module is fixed at the position; and repeating the debugging and impedance matching steps on the microstrip circuit with the fixed copper strip or ind
