Abstract
A multi-feed antenna is described where the antenna is optimized for the natural impedance state per frequency band. Multiple feed points are accessed as a function of frequency and use case to provide a feed port that is operating at the natural impedance state for the antenna structure. Impedance transforming circuits can be applied to the feed point to form impedance matching circuits to transform the antenna impedance to a characteristic impedance of the system or circuit interfacing with the antenna. The impedance transforming circuits can be eliminated and the RF circuitry interfacing with the antenna can be configured to operate at the natural frequency of the antenna.
