Design of high performance magnetoelectric dipole antenna loaded with metasurface
摘要
Abstract
Aiming at the problem of antenna stealth,a magnetoelectric dipole antenna loaded with wide-band polarization conversion metasurface has been proposed,which has realized RCS reduction and im-proved antenna gain in a wide frequency band.The polarization conversion metasurface unit of the designed polarization conversion metasurface unit is greater than 0.9 in the wide band range of 8.4～25.6 GHz,and its arrangement is optimized by genetic algorithm and applied to magnetoelectric dipole antenna.The simu-lation results show that the peak gain in the working bandwidth of 8.9～10.5 GHz is 10.7 dB,which im-proves the radiation performance compared with the reference antenna.The single-station RCS under y-po-larization and x-polarization incident wave achieves RCS reduction in the wide band range of 5.9～29 GHz,and the maximum reduction reaches 25.5 dB and 25.8 dB,respectively.关键词
