Various embodiments of a single structure multiple mode antenna are described. The antenna is preferably of a single layer construction having a plurality of inductor coils positioned on respective opposing substrate sides that are electrically connected. The antenna is also 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.
