Secondary Antenna for Wireless Microphone

A wireless device, comprising:

• a main body;
• an opening within a side surface of the main body;
• at least one antenna disposed within the opening;
• and
• at least one printed circuit board (PCB) configured to enable operation of the antenna, wherein the antenna comprises a modified planar inverted-F antenna (PIFA) structure formed by a single conductive element, a connection element coupled between the conductive element and the PCB to form an antenna feed point, and at least one inductor configured to couple the connection element to a ground plane of the antenna.
