Abstract
Various embodiments of a single structure multiple mode antenna are described. The antenna is preferably constructed having a first inductor coil that is electrically connected in series with a second inductor coil. The antenna is constructed having a plurality of electrical connections positioned along the first and second inductor coils. A plurality of terminals facilitates connection of the electrical connections thereby providing numerous electrical connection configurations and enables the antenna to be selectively tuned to various frequencies and frequency bands. An internal switch circuit is provided that facilitates electrical connection of the various terminals and frequency tuning.
