ABSTRACT:
A distributed loaded antenna system including a monopole antenna is disclosed. The antenna system includes a radiation resistance unit coupled to a transmitter base, a current enhancing unit for enhancing current through the radiation resistance unit, and a conductive mid-section intermediate the radiation resistance unit and the current enhancing unit. The conductive mid-section has a length that provides that a sufficient average current is provided over the length of the antenna.
