Abstract
An example antenna system includes a parasitic element and a symmetrical element fed by a balanced RF signal source. The fed element is operable to couple with the parasitic element, thereby causing the parasitic element to resonate at a first frequency band. Thus, the fed element is operable to act as a balanced capacitive feed for the parasitic element. Also, the parasitic element is symmetrical with respect to a polarity of the fed element.
