Problems solved by technology

[0003] The bandwidth of traditional microstrip planar reflectarray antennas is usually narrow, generally less than 10%, so it is of great significance to realize multi-frequency or aperture multiplexing
However, the double-layer structure has its inherent disadvantages. The upper unit will block the lower layer, and the resonance mode excited by the lower unit will also affect the upper unit. Moreover, the double-layer structure is difficult to align and the processing cost is high.

Abstract

Provided in the invention is an X / Ku-frequency-band double-frequency dual-polarization microstrip-flat-reflective-array antenna comprising a feed source and a microstrip flat reflective array. The feed source is a pyramidal horn antenna. The microstrip flat reflective array contains a plurality of dual-parallel oscillator units; each dual-parallel oscillator units includes two parallel oscillator pasters with different lengths and identical width: a long oscillator paster and a short oscillator paster; and the units are arranged on a dielectric substrate horizontally and longitudinally in a uniform intersected mode. According to the invention, the provided antenna has the good dual-frequency radiation characteristic and has advantages of simple structure, light weight, and low cost.

Description

technical field [0001] The invention belongs to the technical field of antennas, in particular to an X / Ku frequency band dual-frequency dual-polarization microstrip planar reflective array antenna. Background technique [0002] With the vigorous development of radar systems, long-distance communication and space detection technology, the demand for high-gain antennas is increasing. Traditional high-gain antennas mainly include parabolic antennas or array antennas. Although parabolic antennas have high gain and wide operating frequency bands, their volume Large, heavy, and the inherent curved surface structure is expensive to process, especially in the millimeter wave frequency band, and the parabolic antenna lacks wide-angle beam scanning capabilities. The forced-feed large array antenna can meet the requirements of wide-angle beam scanning, but it has the disadvantages of large loss, low efficiency, complex control circuit, and high cost. In order to make up for the shortc...
