ABSTRACT:
A top loaded antenna comprises a spaced pair of top load plate and a ground plate. A matching element integrally formed with a feedline and a shortline is disposed between the top plate and the ground plate for coupling between the plates, eliminating the necessity of separately and individually coupling the feedline element and shortline element to the plates.
