Lightning-protection reflection type high-strength dual-waveband directional antenna

Abstract

The invention relates to a lightning-protection reflection type high-strength dual-waveband directional antenna. The lightning-protection reflection type high-strength dual-waveband directional antenna comprises a metallic reflection cavity, wherein microstrip plates are arranged in the metallic reflection cavity; a multiplexer is arranged on the microstrip plates; a coaxial cable is connected onto a main circuit of the multiplexer; a first radiation oscillator and a second radiation oscillator are respectively connected onto a first branch and a second branch of the multiplexer; a solid antenna housing covers on the first radiation oscillator and the second radiation oscillator; the solid antenna housing is provided with a lightning-protection reflection oscillator; the lightning-protection reflection oscillator is located at the same side of the first radiation oscillator and the second radiation oscillator; the first radiation oscillator and the second radiation oscillator adopt hollow sail-shaped unipolar metal oscillators; the hollow sail-shaped unipolar metal oscillators consist of first metallic straight strips, second metallic straight strips and arc-shaped metallic strips; the first metallic straight strips, the second metallic straight strips and the arc-shaped metallic strips are connected with one another in an end-to-end manner; angles formed by the first metallic straight strips, the second metallic straight strips and the arc-shaped metallic strips are acute angles; and metal blocks are arranged or directly welded on the hollow sail-shaped unipolar metal oscillators so as to form an inner-and-outer embattlement type structure.

Description

technical field [0001] The invention relates to an inner and outer battlement type lightning protection reflective high-strength dual-band directional antenna suitable for flight carriers. Its typical working frequency bands are P band and L band, and it works with vertical polarization. It has high gain, small standing wave, high efficiency, Dual-band work is mainly used in identification systems and communication systems for various flight carrier identities. Background technique [0002] At present, civil aviation systems have installed identification systems that are convenient for air traffic control; various military fighter planes in developed countries in Europe and the United States are equipped with identification friend or foe systems based on Western systems, and their main working band is L-band; Military fighter planes are equipped with an identification friend or foe system based on the Eastern system, and its main working band is the P band; while some workin...

AI Technical Summary

Problems solved by technology

[0004] Existing antennas either can only work in Western systems or in Eastern systems, and there is no antenna system compatible with both systems, and the radome of this type of antenna is not formed by mold casting. The disadvantages are low structural strength, large size, narrow bandwidth, low gain, and can only work in one band
