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 sheathed millimeter wave satellite communication phased array antenna. Multiple modules are arrayed in a planar or non-planar manner through an active sub-array modularized design idea, and a phased array antenna array having an ultra low profile for communication of a large-scale millimeter wave satellite is formed. The low profile design of the millimeter wave phased array antenna is achieved on the basis of the integration design of a radio frequency circuit, applications of a multifunctional chip, utilization of a multilayer microwave plate and other relatively mature processes. The designed antenna system has a low profile and is high in integration level, the cost of the antenna is equivalent to that of the prior art, and the technology is highly mature. The designed antenna enables installing requirements to be conveniently achieved during satellite communication, and a rear-end module can undergo multibeam technology extension according to actual needs. The sheathed millimeter wave satellite communication phased array antenna is technologically feasible and variable.

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...
