Embodiment Construction

[0027] Attached below Figure 1-7 Specific examples of the present invention are described.

[0028] (Such as figure 2 , image 3 Shown) The Ka-band microstrip array antenna based on elastic contact feeding rotating array, including the antenna radiation unit 1, the feeding network layer 2, the antenna base plate 4 and the radio frequency plug-in 3 from top to bottom. The structure of the array antenna is simple, compact, economical and practical.

[0029] The radio frequency plug-in 3 passes through the antenna bottom plate 4 from bottom to top and is screwed and fixed in the antenna bottom plate 4; the top of the radio frequency plug-in 3 is in elastic contact with the feeding network layer 2 for feeding. The radio frequency plug-in 3 is screw-mounted in the antenna base plate 4 to realize the miniaturization design of the array antenna, and the elastic contact feed, compared with the welding feed connection method, is easy to manufacture and process, and is economical a...

Abstract

The invention provides a Ka-band microstrip array antenna based on elastic contact feed rotary array arrangement. The Ka-band microstrip array antenna comprises an antenna radiation unit, a feed network layer, an antenna bottom plate and a radio frequency plug-in from top to bottom, the radio frequency plug-in unit penetrates through the antenna bottom plate from bottom to top and is screwed and fixed in the antenna bottom plate, and the top of the radio frequency plug-in is in elastic contact with the feed network layer for feeding. Compared with the conventional similar antenna, the antenna provided by the invention has the characteristics of small size, miniaturization, widened circular polarization bandwidth, low elevation angle, high gain and easiness in assembly; the antenna is more economical, practical, safe, stable and reliable.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a Ka-band microstrip array antenna based on an elastic contact feeding rotating array. Background technique [0002] Miniaturization, antenna gain, and beam width are very important indicators in satellite communication systems. Conventional Ka-band antennas are limited by size, which increases the difficulty of designing, processing and assembling the antenna and feed structure, which affects the antenna index and cannot meet the application requirements. Therefore, in the case of ensuring that the antenna gain and beam width meet the index requirements, it is necessary to design a new feeding structure that is easier to manufacture and assemble. Contents of the invention [0003] The technical problem solved by the present invention is to provide a Ka-band microstrip array antenna based on an elastic contact feed rotating array. Compared with the p...
