ABSTRACT:
The invention is a novel solution to circumvent the fundamental gain bandwidth limitations of an antenna of a given size by using a traveling-wave (TW) antenna and strongly coupling it with the mounting platform to enlarge the effective size of the antenna. A preferred form of this invention comprises a conducting ground surface generally curvilinear and conformal to said platform, a broadband TW surface radiator positioned above and spaced apart from said ground surface, an impedance matching structure between the surface radiator and the conducting ground surface, and a reactive impedance matching network positioned on the periphery of said surface radiator.
