Abstract

A signal transmission device includes substrates and resonance sections resonating at the predetermined resonance frequency. At least one of the substrates is formed with two or more resonators in the second direction, and the remaining one or two or more of the substrates are each formed with one or more resonators in the second direction, and at least one of the resonance sections is configured by a plurality of resonators opposing one another in the first direction between the 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 on the substrate basis.

First claim

What is claimed is:

1. A signal transmission device, comprising:
a plurality of substrates opposing one another along a first direction;
plural resonators; and
a plurality of resonance sections in a parallel arrangement along a second direction different from the first direction, 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…
