Abstract A novel Koch fractal micro strip antenna was designed by introducing the Koch fractal structure and air layer theory to meet the requirements of wide band, high gain and small size of the UHF detection antenna for high voltage switch cabinet partial discharge. The structural parameters of the antenna model are optimized and analyzed by using the simulation software HFSS. The simulation results are as follows: antenna size is 180mm×180mm, when VSWR<5, detection frequency band is 535~825MHz, and average antenna gain is 1.5dB. The simulation results show that the antenna meets the requirements of ultra-high frequency (UHF) detection in switch cabinet.
