ABSTRACT:
An antenna system for transmitting and receiving, in association with a radio device that develops an H-field and an E-field corresponding to a radio frequency power signal having a voltage and a current, the voltage having a phase relationship to the current. The antenna system includes a Hertz-type radiating element. A phasing and matching circuit is electrically coupled between the Hertz-type radiating element and the radio device. The phasing and matching circuit adjusts the phase relationship between the voltage and the current of the radio frequency power signal so that the H-field and the E-field are in nominal time phase. This enhances the performance of all of the antenna parameters in addition to allowing reduction in size.
