Abstract:
1. A signal transmission device, comprising: a plurality of substrates; plural resonators; and a plurality of resonance sections in a parallel arrangement along a second direction different from a first direction along which the substrates are opposing one another, any of the resonance sections adjacent to each other perform signal transmission in a predetermined passband including a predetermined resonance frequency through electromagnetic coupling therebetween by each resonating at the predetermined resonance frequency, wherein at least one of the substrates is formed with two or more resonators of the plural resonators in the second direction, and the remaining one or two or more of the substrates are each formed with one or more resonators of the plural resonators in the second direction, and at least one of the resonance sections is configured by a plurality of resonators of the plural resonators opposing one another in the first direction between the substrates, the plurality of resonators comprising at least two resonators, the at least two resonators being from different substrates, the opposing resonators form a coupled resonator resonating as a whole at the predetermined resonance frequency through electromagnetic coupling in a hybrid resonance mode, and in a state that the substrates are separated away from one another to fail to establish electromagnetic coupling thereamong, the resonators forming the coupled resonator resonate at any other resonance frequency different from the predetermined resonance frequency for each substrate, the signal transmission device further comprising: a first input/output terminal connected directly physically at least to a first resonator of the plurality of resonators, the first resonator configuring a first resonance section among the resonance sections, or electromagnetically coupled to the first resonator with a spacing therefrom; and a second input/output terminal connected directly physically at least to a second resonator of the plurality of resonators, the second resonator configuring any of the resonance sections other than the first resonance section, or electromagnetically coupled to the second resonator with a spacing therefrom, wherein in the state that the substrates are opposing each other in the first direction, signal transmission is performed between the substrates or in each of the substrates, and the first input/output terminal is connected with a filter member allowing passage of a signal of the predetermined passband and interrupting passage of a signal of the other resonance frequency out of a range of the predetermined passband.
