Abstract

A combined, compact battery holder and antenna apparatus. The combined, compact battery holder and antenna apparatus includes a dielectric battery holder and a conductive antenna element having a radiating arm that is supported by the dielectric battery holder. When mounted on a printed circuit board (PCB), the dielectric battery holder maintains the radiating arm of the conductive antenna element at a constant height above a ground plane on the PCB. The compact, combined battery holder and antenna apparatus may be beneficially adapted and configured for use in a variety of electronic devices including, for example, wireless headsets or headphones, cellular communications devices, personal digital assistants (PDAs), and may be adapted and configured to operate according to various types of wireless technologies such as Bluetooth, Wi-Fi and cellular wireless technologies.
