Problems solved by technology

In this system, the Ku frequency band and the Ka frequency band are independent phased array antennas, which can be time-shared or simultaneous when working, and have certain flexibility. However, the volume occupied by the antenna in this way is large, which is not conducive to the antenna Economical application of the system in terms of volume, weight, power consumption, etc.

Abstract

The invention discloses a broadband multi-mode satellite communication phased array antenna which belongs to the field of electronic information technology. The antenna includes receiving array face,transmitting array face, integrated information integrated platform, power supply and distribution layer, distributed power supply, inertial system, tracking receiver, condition monitoring and monitoring control, satellite communication terminal, thermal control system and supporting base. The receiving and transmitting arrays work in Ku, Ka. The design idea of the antenna can not only ensure thesimultaneous operation of the antenna transmitting and receiving, but also ensure that the antenna transmitting and receiving have their own working or standby functions, especially suitable for broadband satellite communication on mobile carrier, but also can be used in the fields of phased array feed of reflector antenna, phased array feed of dragon wave lens and so on.

Description

technical field [0001] The invention relates to the technical field of electronic information, in particular to a broadband multi-mode satellite communication phased array antenna. Background technique [0002] In the traditional field of electronic information, there are many ways to implement broadband satellite communication antennas, which are specifically manifested in the following characteristics: [0003] 1. Antenna system combining broadband feed and reflector. The technology of this method is mature, and the feed source is designed for broadband, and the feed network is designed for broadband and wave splitting, which can realize the capability of broadband satellite communication. However, the antenna form of this method is relatively simple, and the beam pointing needs to be controlled by a mechanical servo structure. On a moving carrier platform, its tracking speed is relatively slow. [0004] 2. Carry out Ku / Ka dual frequency work through broadband passive ar...
