Abstract:
A method of providing a single structure multiple mode antenna having a unitary body construction is described. The antenna is preferably constructed having a first inductor coil portion that is electrically connected in series with a second inductor coil portion. 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 having numerous electrical connection configurations and enables the antenna to be selectively tuned to various frequencies and frequency bands.
