Claim Text:
1. An electromagnetic coupling structure used in a frequency band of a microwave zone, the electromagnetic coupling structure comprising: a laminated body that is laminated with an inner dielectric layer interposed between inner conductive layers that are a plurality of ground layers; one pair of outer dielectric layers that face each other with the laminated body interposed between the outer dielectric layers; and one pair of outer conductive layers that face each other with the one pair of outer dielectric layers interposed between the outer conductive layers, wherein each one of the one pair of outer conductive layers includes a wiring portion and a conductive patch portion disposed at a front end of the wiring portion, the conductive patch portion has a portion longer than a width of the wiring portion in a direction perpendicular to an extending direction of the wiring portion, a hole passing through the inner dielectric layer and the inner conductive layers that are the plurality of ground layers is formed in the laminated body, and a tube-shaped metal film formed on an inner wall of the hole electrically connecting the inner conductive layers that are a plurality of ground layers, whereby the one pair of outer conductive layers are electromagnetically coupled.
