A method of reducing sidelobes of an antenna induced by a blockage in a radome covering the antenna, which includes providing at least one passive tuning element between the antenna and the blockage, and adjusting the position of the tuning element to reduce the blockage-induced sidelobes. An antenna apparatus which includes an antenna, a radome covering the antenna and including a blockage tending to induce a sidelobe in the radiation pattern of the antenna, and at least one passive tuning element between the antenna and the blockage for reducing the blocking-induced sidelobes.
