The gain of pyramidal horns with different configurations was simulated and the high power microwave(HPM) measurement antenna with low gain was selected accordingly. The numerical simulation and experiment were carried out on the pyramidal horn’s pulse response and gain with and without flange and waveguide. The selected pyramidal horn will not distort the waveform of the short microwave pulse with 20 ns pulse width, and thus it can be used in the measurement of short microwave pulse. The influence of the flange and the 300 mm waveguide on the gain is less than 0.2 dB. Moreover, the pattern of the pyramidal horn is smooth and the beam width is about 50° for HPM measurement. The selected pyramidal horn is qualified for high power microwave radiation field measurement in complicated enviro
