Embodiment Construction

[0022] In order to effectively reduce the longitudinal volume of the antenna. And to improve the performance of the antenna, the embodiment of the present invention provides a millimeter-wave one-dimensional single-pulse dual-plane reflective antenna. In the technical solution of the present invention, by using two reflectors up and down, and setting the feed source on the lower reflector The central position of the antenna reduces the longitudinal volume of the antenna while improving the performance of the antenna. In order to make the object, technical solution and advantages of the present invention clearer, the following non-limiting examples are taken as examples to further describe the present invention in detail.

[0023] Such as figure 1 As shown, a millimeter-wave one-dimensional single-pulse dual-plane reflective antenna according to an embodiment of the present invention, the millimeter-wave one-dimensional single-pulse dual-planar reflective antenna includes a po...

Abstract

The invention relates to a millimeter wave one-dimensional single-pulse biplane reflecting antenna. The millimeter wave one-dimensional single-pulse biplane reflecting antenna comprises a polarization grid reflecting board, a polarization twist and focusing reflecting board and a feed source, wherein the polarization twist and focusing reflecting board is located below the polarization grid reflecting board and is electrically insulated from the polarization grid reflecting board; the feed source is arranged in the center of the polarization twist and focusing reflecting board and penetrates through the polarization twist and focusing reflecting board. The millimeter wave one-dimensional single-pulse biplane reflecting antenna has the advantages that on the condition of ensuring the performance, the longitudinal dimension is effectively decreased. The feature of a low section is achieved, the purpose of reducing the overall dimension is achieved, in addition, the feed source shielding effect can be effectively avoided, the overall radiation performance of the antenna is improved, the polarization purity can be effectively improved, the cross-polarization rejection ratio can be greatly improved by adjusting the dimension of a polarization grid of an upper polarization grid layer, and therefore higher polarization purity is obtained.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a millimeter-wave one-dimensional single-pulse double-plane reflection antenna. Background technique [0002] The planar microstrip reflectarray antenna adopts the air-fed form, which combines the advantages of high efficiency of the reflectarray antenna and the advantages of lightness and easy processing of the microstrip array antenna. However, similar to the traditional reflector antenna, the traditional planar microstrip reflectarray antenna also has the disadvantage of large longitudinal size, and its three-dimensional structure makes installation and carrying troublesome, which greatly limits its development and application. [0003] The monopulse radar antenna can form sum and difference beams to determine the distance and azimuth of the target. Compared with the traditional multi-aperture monopulse radar, the single-aperture multimode monopulse radar has t...
