Abstract:
The purpose of the present invention is to realize a wireless device that has high heat dissipation performance and can be manufactured at low cost. The wireless device according to one embodiment of the present disclosure comprises: a wireless-signal-radiating element or reflective element; and a heat dissipation unit (120) that dissipates to the outside the heat generated by a heat-generating source that includes the radiating element or the reflective element. The heat dissipation unit (120) is constituted from a solid material having thermal conductivity and electrical conductivity, and has a heat dissipation plate (122) and a plurality of heat dissipation fins (121) provided on the heat dissipation plate (122) and arranged on the same side as the radiating element or the reflective element with respect to the heat dissipation plate (122). The heat dissipation fins (121) form a periodic structure in at least one direction on the heat dissipation plate (122). The tips of the plurality of heat dissipation fins (121) constitute a virtual reflective surface (123) that reflects incident waves to the plurality of heat dissipation fins (121).
