Miniaturized missile-borne radar antenna with high transmit-receive isolation

According to the miniaturized missile-borne radar antenna with high transceiving isolation, the microstrip patch antenna array which is fed in series is adopted as the transceiving antenna, so that the antenna gain is improved, and meanwhile, the feeding form between the antennas is simplified; meanwhile, the electromagnetic band gap structure array is arranged between the transmitting and receiving antennas, and further, the radiation patches of the electromagnetic band gap structure units are subjected to grooving design, so that surface wave coupling between the transmitting and receiving antennas is reduced, the isolation between the transmitting and receiving antennas is improved, the setting size of the antennas and the setting distance between the transmitting and receiving antennas are reduced, and the antenna performance is improved. And miniaturization of the missile-borne antenna is realized. Secondly, the transverse widths of the units of the microstrip patch antenna array for series feed are sequ
