Abstract
An antenna with a curved shape may be mounted behind a curved antenna window. The antenna may have an antenna resonating element such as an inverted-F antenna resonating element and may have an antenna ground. The antenna resonating element may be formed from patterned metal traces on a flexible printed circuit. The flexible printed circuit may have ground traces that run along a peripheral edge of the flexible printed circuit. The antenna ground may be formed from a metal can with walls surrounding a cavity having an opening. The metal can may have a lip formed from bent portions of the walls. The flexible printed circuit may be soldered to the lip so that the ground traces are shorted to the can. A cable connector may be mounted on a bent tab in the flexible printed circuit that extends through a notch in the lip.
