Abstract: PROBLEM TO BE SOLVED: To secure the matching of impedance between the microwave circuits and to reduce the loss of a transmission circuit while keeping a gap between the microwave circuits by adding an impedance transformer of frequency to every microwave circuit to set a specific rate against the intra-transmission line wavelength. SOLUTION: An impedance transformer having length of 1/4 intra- transmission line wavelength λg is prepared between the microstrip line substrates 7c and 7d and a conductive ribbon or wire 5.
