IPC: H01P3/06
Filed: 1984-07-12
Abstract: PURPOSE:To supply a high frequency power efficiently by inserting a capacitor on the way of a transmission line connected to a loop antenna to cancel the reactive component of a surge impedance on the transmission line and weaken thereby decreasing the standing wave ratio. CONSTITUTION:A couple of electrode plates, 10, 10 are opposed on the way of an inner conductor 7 with a predetermined interval so as to a static capacitance required as a capacitor 9.
