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

Abstract

A guiding high-strength dual-waveband directional antenna comprises a metal reflection cavity. A micro-strip plate is arranged in the metal reflection cavity, a multiplexer is arranged on the micro-strip plate, a coaxial cable is connected to a main path of the multiplexer, a first radiation oscillator and a second radiation oscillator are connected to a first branch and a second branch of the multiplexer respectively and covered by a solid antenna cover, and the first radiation oscillator and the second radiation oscillator are hollow sail-shaped monopole metal oscillators. Each hollow sail-shaped monopole metal oscillator comprises a first metal straight strip, a second metal straight strip and an arc metal strip, which are in end-to-end connection and form three acute angles, metal blocks are arranged on or directly welded to the hollow sail-shaped monopole metal oscillators to form inner and outer battlement structures.

Description

technical field [0001] The invention relates to an inner and outer battlement-type directing type 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 working fighter planes ...
