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.
