Abstract
A wall-mountable wireless control device may include an antenna (e.g., a slot antenna or a hybrid slot-patch antenna) for transmitting and/or receiving radio-frequency signals. The wireless control device may comprise a user interface, an antenna, a radio-frequency communication circuit, a control circuit, and/or a conductive faceplate. The radio-frequency communication circuit may be configured to transmit or receive radio-frequency signals via the antenna. The user interface may be configured to receive a user input. The conductive faceplate may be configured to operate as a radiating element of the antenna when the conductive faceplate is mounted to the wireless control device and the user interface is received in the opening of the conductive faceplate. The conductive faceplate may comprise a conductive material arranged over a plastic carrier, for example, the conductive material may be provided adjacent to greater than or equal to approximately 85% of the front surface.
