Study on the Effective Receiving Area of UAV WIFI Antenna Under High-Power Microwave Radiation

UAV WIFI antenna is susceptible to high power microwave electromagnetic environment, this paper established the high frequency simulation model of WIFI antenna, simulated and calculated the electromagnetic coupling effect under the action of high power microwave environment, and analyzed the coupling effect of high power microwave on the UAV WIFI communication antenna port under different incidence angles; and studied that the antenna will change the effective receiving area under the action of HPM when the pulse parameters such as injected pulse repetition frequency and injected pulse width are changed. It is also verified through experiments that the area of WIFI antenna under high power microwave is only related to the irradiation angle, and has nothing to do with the pulse parameters such as pulse repetition frequency and pulse width.
