ABSTRACT:
A phased array antenna having a low profile (approximately ⅛ wavelength) wide bandwidth (approximately 50%). The invention teaches making such an antenna using open channel resonators and monopole wave launchers. The wave launchers may conveniently be made on circuit card assemblies with strip lines that mimic coaxial cable monopole wave launchers. The channel resonators may be made in sections that are soldered to the circuit card assemblies. The circuit card assemblies have plated through holes that trace the edges of the resonator sections to provide electrical continuity.
