ABSTRACT:
Impedance adjusting elements for a microstrip circuit of the kind employing a signal transmission line connected to an active circuit element and impedance matching elements, such as parallel-connected open-ended stubs, are formed of one or more wire elements arranged in proximity to the transmission line and the open-ended stub and connected at one end to the ground plane on the side of the substrate opposite the transmission line, wherein the free end of the wire elements can be freely moved, thereby adjusting the spacing of the wire elements from the respective signal path and open-ended stub and adjusting the angle of intersection of the wire elements and the respective signal path and open-ended stub, so that the effective impedances of the circuit can be controlled.
