Problems solved by technology

Since the TEM horn antenna radiates spherical waves and has no spatial focusing capability, the forward radiation field strength is low. At the same time, in order to fix the TEM horn antenna, a fixed structure of the antenna needs to be specially made, which increases the overall size of the antenna.

Embodiment

[0032] Such as figure 1 As shown, a kind of ultra-broadband electromagnetic pulse radiation antenna structure includes an upper pole plate 1, a lower pole plate 2, a casing 3 and a cable head (not shown in the figure);

[0033] The upper plate 1 and the lower plate 2 form a TEM horn with gradually changing impedance; the characteristic impedance at the initial end is 50Ω, and the characteristic impedance at the aperture end is determined by the width and height of the upper and lower plates at the aperture. The overall appearance of the shell 3 is a trapezoidal structure. The shell 3 includes a bottom plate 4, an upper side plate 5, and a lower side plate 6; the upper plate 1, the lower plate 2, the bottom plate 4, the upper plate 5, and the lower plate 6 are all conductive. Good metal material.

[0034] Both the starting ends of the upper pole plate 1 and the lower pole plate 2 are connected to the bottom plate 4, and the starting ends of the upper pole plate 1 are connected...

Abstract

The invention discloses an ultra-wide-spectrum electromagnetic pulse radiation antenna. The antenna adopts a shell to connect the upper and lower pole plates into a whole. When the current loop is formed to improve the forward radiation ability of the antenna, it can also be used as an antenna. The supporting structure makes the antenna structure more reasonable. The antenna includes an upper pole plate and a lower pole plate, and the upper pole plate and the lower pole plate form a TEM horn form with gradual impedance change, and also includes a shell and a cable head; the shell includes a bottom plate, an upper side plate and a lower side plate; the upper pole plate and The starting ends of the lower pole plates are connected to the bottom plate, and the starting ends of the upper pole plates are connected to the core wires of the cable head; one end of the upper side plate is connected to the upper edge of the bottom plate, and the other end is connected to the The aperture end is connected; one end of the lower side plate is connected to the lower edge of the bottom plate, and the other end is connected to the aperture end of the lower plate.

Description

technical field [0001] The invention belongs to electromagnetic pulse measurement technology, and relates to an antenna, in particular to an ultra-wide-spectrum electromagnetic pulse radiation antenna. 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 electromagnetic pulse radiation antenna is the core component of the ultra-broadband microwave system, and its function is to radiate the ultra-broadband pulse generated by the pulse source to a designated area with a certain beam width. [0004] At p...
