Problems solved by technology

The dual-feed common-reflection surface radiation technology is an effective way to expand the beam width of the radiation field. By distributing the feed power equally to the two feed sources for radiation and forming two beams in space, the beam width of the radiation field can be achieved. doubled, but the consequence is that the radiation field strength is reduced, resulting in a shorter operating distance

Embodiment

[0025] Such as figure 1 As shown, a dual-feed common current loop ultra-wideband radiation antenna, which includes two identical feeds (such as figure 1 The first horn feed source 1 and the second horn feed source 2) are respectively placed on both sides of the focal point of the parabolic reflector 3, the main axes of the first horn feed source 1 and the second horn feed source 2 and the parabolic reflector 3 The direction of the optical axis is parallel; the line connecting the radiation centers of the two feed sources and the focus of the parabolic reflector are on the same straight line. The polarization directions of the two feeds are opposite, the high voltage plate of the first horn feed 1 and the high voltage plate of the second horn feed 2 diffuse in the same direction; the low voltage plate of the first horn feed 1 and the second The low-voltage plate of the two-horn feed 2 is back diffused; the distance between the two feeds can be adjusted according to the require...

Abstract

The invention discloses a double-feed-source common-current-loop ultra-wideband radiation antenna structure. The antenna structure can remarkably improve the radiation field intensity while improvingthe beam width of a radiation field. The technical scheme is as follows: two same horn-type feed sources are arranged on two sides of a focal point of a parabolic reflecting surface in parallel, the main axis directions of the horn-shaped feed sources are parallel to the optical main axis of the parabolic reflecting surface, the polarization directions of the two horn-shaped feed sources are opposite, the high-voltage poles are both located on the inner side, and the high-voltage pole plates of the two horn-shaped feed sources are simultaneously connected through one current loop, so that theradiation efficiency of the two feed sources is simultaneously improved.

Description

technical field [0001] The invention belongs to the electromagnetic pulse measurement technology, and relates to an antenna, in particular to a double-feed common current loop ultra-wideband radiation antenna structure. Background technique [0002] Ultra-broadband electromagnetic pulses usually refer to pulse fronts or pulse widths in sub-nanoseconds (10 -10 s) Transient electromagnetic pulses with a magnitude and a spectrum range of tens of MHz to several GHz, which have broad spectrum and short pulse characteristics similar to nuclear electromagnetic pulses. It has been widely used in many fields such as target detection, target recognition, electromagnetic damage, electromagnetic compatibility, and biomedicine. [0003] The ultra-broadband pulse radiation antenna is the core component of the ultra-broadband high-power microwave system. Its function is to radiate the ultra-broadband pulse generated by the pulse source to the designated area with a certain beam width, and...
