ABSTRACT:
The present invention is directed to a broadband electric-magnetic antenna apparatus and method. The present invention teaches a variety of electric antennas suitable for use in the present invention as well as a variety of magnetic antennas suitable for use in the present invention. Combination of a broadband electric antenna element and a broadband magnetic element to create a broadband electric-magnetic antenna system is discussed. This invention further teaches systems for using a broadband electric magnetic antenna system to radiate or receive quadrature signals.
