Technologies directed to a radio frequency (RF) structure that provides an electrically insulating gap between a ground plane of a circuit board and a chassis at direct current (DC) and an electrical connection between the ground plane and the chassis at RF frequencies. One RF structure includes a first conductor electrically coupled to the ground plane and a second conductor electrically coupled to the chassis. A physical arrangement of a portion of the first conductor and a portion of the second conductor causes the RF structure to provide an electrically insulating gap between the ground plane and the chassis at DC and an electrical connection between the ground plane and the chassis at RF frequencies.

A wireless communication device includes: an antenna including an antenna element, and a ground conductor; an IC connected to the antenna; and a metal member arranged to face the antenna. The ground conductor includes one end and the other end in the X direction. The metal member includes a metal plate, and a projection protruding from the metal plate toward the antenna. The projection is arranged at a position of overlapping with the end of the ground conductor as viewed in the −Z direction. Such a configuration improves the transmission and reception gains at the communication frequency of a radio element.
