Abstract
[Background]With the rapid development of high-power microwave technology,planar array antennas with high-power capacity,high aperture efficiency and low profile characteristics become more and more attractive.[Purpose]To improve the performance of high power microwave planar array antennas,a mode fission antenna with low profile applied to the C band is proposed to enhance the power capacity and aperture efficiency.[Methods]The simulation and experimental research were conducted on this form of antenna.[Results]The simulation results show that the aperture efficiency of the designed mode fission antenna is as high as 95.2%,and the power handling capacity is higher than 200 MW/m2.The low power and high power experiments reveals that,the port reflection is lower than-20 dB at the center frequency of 4.3 GHz,with realized gain of 34.6 dBi and aperture efficiency of 91.9%.Power-handling capacity is higher than 200 MW/m2,radiation pulse width not less than 50 ns.[Conclusions]It achieves higher aperture efficiency while ensuring power capacity,and has high potential for application.关键词
