Abstract

See full text

A structure member is mounted in a communication apparatus including a conductive housing incorporating a dielectric substrate on which a high-frequency circuit is mounted. The structure member includes a pass member which passes a harmonic current component of an operating frequency generated in the dielectric substrate when the high-frequency circuit operates, and a suppression member having an EBG structure which suppresses a predetermined current component of the operating frequency. The structure member is provided between the dielectric substrate and the conductive housing. The suppression member is disposed along a current path of a harmonic current component flowing in the pass member.
