Abstract: Disclosed herein is a controlled reception pattern antenna that prevents the degradation of anti-jamming performance in a compact array antenna by increasing the antenna gain at a low elevation angle. The proposed antenna includes a radiator for receiving a satellite signal, a ground platform in which the radiator is arranged, and a radiating slot formed in the ground platform. By simply forming a radiating slot in the ground platform, antenna gain may be increased at a low elevation angle. Therefore, it is possible to maintain anti-jamming performance and to reduce the size of the array antenna.
