Abstract

The invention relates to a receiving antenna for a high-power microwave radiation field measuring system. According to the receiving antenna, the characteristics of small size, wide band and high power capacity of a coaxial line are utilized, the structure of the receiving antenna is designed on the basis of a TEM (transverse electric and magnetic field) horn to which coaxial feed can be easily applied, and a radiation mode formed by an outer surface current of a coaxial feeder of the TEM horn is restrained through improvement of antenna structure, so that the antenna has good directional diagrams and standing waves in terms of working band. Through cooperative use of the receiving antenna and other devices of the radiation field measuring system, the size of the measuring system can be effectively reduced, and requirements of L-band high-power microwave radiation measurement can be met.

Description

technical field [0001] The invention belongs to the high-power microwave measurement technology in the field of high-power microwave technology, in particular to a receiving antenna matched with a miniaturized high-power microwave radiation field measurement system. Background technique [0002] High-power microwave refers to strong electromagnetic radiation with a frequency range from 300MHz to 300GHz and a peak power greater than 100MW or an average power greater than 1MW. High-power microwaves have important applications in the fields of radar, communication, nuclear fusion heating, material processing, and directed energy. [0003] The receiving antenna is one of the most common components in the high-power microwave measurement system. In the high-power microwave measurement system, it is necessary to use the antenna to capture the microwave signal emitted by the high-power microwave source. At present, the common receiving antennas of high-power microwave radiation fi...
