A new waveguide slot array antenna with two artificial magnetic conductor (AMC) side walls is proposed. The AMC layers reflect the wave with different phase delays through the waveguide side walls which compensate the requirement of slots offset and improve the antenna gain and sidelobe level (SLL). A five slots array antenna with AMC layers is designed and measured which shows 9 dB SLL reduction and 1.5 dB gain enhancement with compact size compared with the conventional Elliot one. These results clarify the ability and capability of the proposed design approach.
