Embodiment Construction

[0026] Below, combine Figure 1-Figure 5 The present invention will be further described.

[0027] In a skinned millimeter-wave satellite communication phased array antenna 1, such as figure 1 As shown, it is formed by arranging a plurality of active sub-array modules according to certain rules, N is a natural number, and the arrangement method is not limited to a plane, and can also be a multi-plane array or a conformal arrangement. Among them, the analog active sub-array 2 itself has independent antenna functions, and has the characteristics of expandable arrangement, and the analog active sub-array 2 can be selected according to the requirements of the system to form an array. The entire skinned millimeter-wave satellite communication phased array antenna has an ultra-low profile.

[0028] In a skinned millimeter-wave satellite communication phased array antenna 1, such as figure 2 , image 3 and Figure 4 As shown, the simulated active subarray 2 is a skin structure ...

Abstract

The invention discloses a skinned millimeter-wave satellite communication phased array antenna, which adopts the modular design concept of active sub-arrays, and forms a large-scale millimeter-wave satellite with an ultra-low profile by forming a planar or non-planar array of multiple modules. Phased array antenna for communication. Based on relatively mature technologies such as the integrated design of radio frequency circuits, the application of multi-functional chips, and the use of multi-layer microwave boards, the low-profile design of millimeter-wave phased array antennas is realized. The designed antenna system has both low profile and high integration, and the cost is equivalent to the existing level, and the technology maturity is high. The antenna designed by the invention can conveniently realize installation requirements when performing satellite communication, and can extend the multi-beam technology to the back-end modules according to actual needs, which has technical feasibility and variability.

Description

technical field [0001] The technical field involved in the present invention covers the field of millimeter wave electronic information, including radar, communication, countermeasures, remote sensing and telemetry, etc., and is specifically a skinned millimeter wave satellite communication phased array antenna. The present invention is also particularly applicable to the field of satellite communication. In order to realize the installation requirements of low-profile antenna terminals and covert communication between satellites and ground terminals, the installation platform can be equipped with fast and conformal designs to provide ultra-low profile for satellite communication terminals. Profile Phased Array Antenna System. Background technique [0002] In the field of millimeter-wave phased array antennas, since the antenna array needs to scan at a large angle, the spacing between the antenna elements is very small, usually only half of the working wavelength, especially...
