RESONANCE COUPLER AND TRANSMISSION DEVICE

摘要

A resonance coupler according to one aspect of the present disclosure includes first resonance wiring and second resonance wiring. The first resonance wiring includes first open loop wiring, first input/output wiring extending outwardly from a first connection portion of the first open loop wiring, and first stub wiring extending inwardly from a second connection portion of the first open loop wiring. The second resonance wiring includes second open loop wiring, and second input/output wiring extending outwardly from a third connection portion of the second open loop wiring. The first stub wiring includes a first connection end connected to the second connection portion and a first open end on an opposite side. A wiring length from the first connection portion to the first open end is one-quarter of a wavelength of an nth-order harmonic of a radio-frequency signal, where n is an integer not less than 2.

1. A resonance coupler comprising:
first resonance wiring which includes
first open loop wiring having a first open portion,first input/output wiring extending outwardly from a first connection portion of the first open loop wiring, andfirst stub wiring extending inwardly from a second connection portion of the first open loop wiring, the first stub wiring including a first connection end which is connected to the second connection portion of the first open loop wiring and a first open end on a side opposite to the first connection end; and second resonance wiring which includes
second open loop wiring having a second open portion, the second open loop wiring facing the first open loop wiring, andsecond input/output wiring extending outwardly from a third connection portion of the second open loop wiring, wherein a radio-frequency signal is isolatedly transmitted between the first open loop wiring and the second open loop wiring, and a wiring length from the first connection portion of the first open loop wiring to the first open end of the first stub wiring is one-quarter of a wavelength of an nth-order harmonic of the radio-frequency signal, where n is an integer not less than 2.
