Abstract
The present invention provides an aperture-fed patch antenna assembly that is recessed into a conductive surface of an external shell of an electronic device. In one embodiment, an antenna feed attached to a removable core of the electronic device may be removed from the external shell without requiring a manual disconnecting of the antenna feed from a wireless radio modem in the electronic device. The patch antenna assembly includes a shim having an aperture therein and positioned between a primary dielectric and a printed circuit board to create a secondary dielectric between the primary dielectric and the printed circuit board. In one embodiment, the primary dielectric is ceramic and the shim is plastic.
