Abstract: A compact antenna system that provides an antenna capable of transmitting and/or receiving radio signals configured on a flexible substrate material supporting user control interface buttons. In an embodiment, an antenna may be formed on a user control interface button flex between the wire traces used to couple the user control interface buttons to a printed circuit board. In order to prevent the interference on the antenna that may be caused when current passes through the wire traces coupling the user control interface buttons to the printed circuit board, an RF choke (i.e., LC filter) circuit and bypass capacitors may be configured along each wire trace. In another embodiment, the wire trace coupling a user control interface button to the printed circuit board may be configured to serve the dual purposes of coupling the user control interface button to the printed circuit board; and functioning as an antenna capable of transmitting and/or receiving wireless radio signals.
