Abstract
An electronic device may be provided with sidewalls and a conductive plate. A segment of the sidewalls may form a radiating arm of an antenna. A display may be mounted to the sidewalls. The display may include a conductive frame and a flexible printed circuit. The flexible circuit may have a bend. Conductive foam may short a conductive trace on the flexible circuit to the conductive frame near the bend. Low injection pressure overmolding (LIPO) may be molded over the flexible circuit, the foam, and the frame. A conductive spring may short the frame to the conductive plate. The spring may include a wider and/or thinner portion that optionally includes one or more notches for reducing its inductance. The conductive plate, the spring, the frame, the foam, and the conductive trace may form part of the antenna ground for the antenna.
