Abstract:
Provided is a heat dissipation sheet-integrated antenna module which maintains a heat dissipation performance and an antenna performance to be equal to or better than those of a structure where a heat dissipation sheet and an antenna module are separated. The presented heat dissipation sheet-integrated antenna module is configured by coupling a heat dissipation sheet having a slit formed therein to an upper or lower part of an antenna pattern. Therefore, the antenna pattern of the antenna module is operated as an auxiliary heat dissipation member or the heat dissipation sheet is operated as an auxiliary radiator of the antenna module.
