ABSTRACT:
A device for reducing the backlobe radiation from small aperture antennas is shown to comprise a thin hemispherical radome having both radio frequency energy absorbing and reflecting materials attached thereto. The absoring material dissipates a portion of the edge currents existing on the antenna aperture, while the reflecting material intercepts a portion of the energy radiated from the antenna and reflects that portion back to the edge of the antenna to produce destructive interference with the edge currents.
