ABSTRACT:
An internally mounted broadband antenna utilizing two resonators and a reactive ground feed is disclosed. A nonconductive notch separates a conductive surface into two portions which are coupled to a respective one of each resonator. Each resonator is a microstrip conductor forming a transmission line with its respective conductive surface portion. Coupling to the antenna is accomplished by connection across the notch.
