摘要：

In order to meet the requirement of miniaturization on high power microwave (HPM) measuring system at L-band, an miniaturized HPM measuring antenna with coaxial feeding is designed. On the basics of the structure of TEM horn, the electric-magnetic vibrator structure is used to improve the performance of radiation pattern. The relationship between electric-magnetic vibrator structure and the character of the gain, the radiation pattern and VSWR is investigated by theoretical analysis and numerical calculation. The structure size is 100 mm×100 mm×100 mm. It shows that with the frequency varying from 1.2 to 1.8 GHz, the gain increases from 2.8 to 6.1 dB linearly, and the width of the radiation beam is smooth and larger than 70°. In the meanwhile, the VSWR is less than 1.5. ©, 2015, Editorial Office of High Power Laser and Particle Beams. All right reserved.
