Abstract
A top-loaded low profile antenna for data transponders includes an antenna pin mounted vertically, affording vertical polarization for the antenna, an aluminum plate mounted in a horizontal plane and connected to an upper end of the pin, providing top-loading of the antenna, the plate being supported by a lucite frame mounted on an upper surface of the data transponder and which also dielectrically loads the antenna feed region. The load plate and lucite frame enclose the antenna pin so that the antenna is less susceptible to vandalism, and the top-loading results in a reduction in the height of the antenna structure improving the aesthetics of the antenna and data transponder installation.
