Abstract

The invention discloses a missile-borne dual-frequency active antenna, which comprises a structural cavity, an RDSS antenna, a sky-chain antenna, a duplexer, a low noise amplifier and a connector. Theduplexer is fixed in the first cavity of the structural cavity, and the low noise amplifier is mounted on the surface of the duplexer. The RDSS antenna and the sky-chain antenna are respectively installed in the second cavity and the third cavity which are spaced apart from the first cavity and electrically connected with the duplexer through the inner conductor connector. One end of the connector is electrically connected with the low noise amplifier, and the other end protrudes from the bottom of the structural cavity to connect the external device. The internal components are shielded integrally and separated by a structural cavity with a plurality of cavities to improve the mutual isolation and anti-interference of the dual antennas. The invention improves the anti-interference ability, reduces the volume of the active antenna and ensures the output signal quality, and has the advantages of high integration degree, low noise coefficient, high isolation degree and high inhibition degree.

Description

technical field [0001] The invention belongs to the technical field of satellite communication, and more specifically relates to a missile-borne dual-frequency active antenna. Background technique [0002] RDSS (Radio Determination Satellite Service) is a satellite radio determination service. The distance measurement and position calculation from the user to the satellite cannot be completed by the user itself, but must be completed by an external system through the user's response. Its characteristic is that through the user's response, while completing the positioning, it completes the user's position report to the external system, and also realizes the integration of positioning and communication, and realizes the integration of NAVCOMM in the same system; Tianlian Satellite is a subsidiary of China Aerospace Science and Technology Corporation The tracking and data relay satellite mainly developed by the affiliated China Academy of Space Technology (CAST) provides data re...
