Abstract : An electrostatically figured directional antenna array for deployment in outer space having means for suppressing sidelobe responses. A portion of the reflector surface symmetric about its center is vibrated by electrostatic controls to change the amplitue and phase of the sidelobe signals whereby the latter can be eliminated by passive filters or time averaging circuitry.
