Abstract

In one embodiment, an apparatus includes: an antenna mount provided for an antenna; a first portion of an electrically conductive heat coupler provided for the antenna mount, wherein the first portion of the electrically conductive heat coupler reflects electromagnetic radiation associated with the antenna; and a second portion of the electrically conductive heat coupler electrically coupled to the first portion, where the second portion is shaped for arrangement in association with the placement of one or more electrical components on a substrate in order to draw heat away from at least one of the one or more electrical components and dissipate the heat over a combined surface area of the first and second portions of the electrically conductive heat coupler.
