Abstract
An electronic device may include an antenna element, coil, sensor board, and grounding ring structures. The coil may receive wireless charging signals through the grounding ring structures. The grounding ring structures may include concentric ring-shaped traces separated by at least one gap. The ring-shaped traces and gaps may configure the grounding ring structures to short antenna currents at relatively high frequencies from the antenna element to a ground trace on the sensor board while blocking currents at relatively low frequencies. The grounding ring structures may include conductive wings that increase capacitive coupling between the grounding ring structures and the antenna element. The grounding ring structures may be soldered to the antenna element. The antenna element and the grounding ring structures may be formed from traces patterned on the same substrate. The ground trace may form part of an antenna without substantially impairing wireless charging efficiency of the coil.
