Problems solved by technology

At present, the existing technology generally adopts the traditional parabolic self-tracking antenna form, and under the same gain condition, the volume of the parabolic self-tracking antenna will not be less than 600mm×600mm×240mm, the volume is too large, which greatly increases the weight of the vehicle-mounted antenna, and The frequency coverage is narrow. With the development of multi-target telemetry vehicle station technology, the traditional parabolic self-tracking antenna can no longer meet the demand

Abstract

The invention discloses a broad-band double-circular-polarization panel self-tracking antenna, and the antenna comprises an antenna array, a double-circular-polarization sub-array feed network, a supporting column, a filtering low-noise amplifier assembly, a sum-difference modulator combination, an antenna cover, an antenna bottom plate, an antenna cavity, and a cover plate. The antenna array is connected with the double-circular-polarization sub-array feed network through the supporting column, and the double-circular-polarization sub-array feed network is fixed on the antenna bottom plate. One end of the supporting column passes through a corresponding through hole of the antenna array to be fixed through a screw, and the other end of the supporting column passes through the double-circular-polarization sub-array feed network and the antenna bottom plate to be fixed on the antenna cavity. The filtering low-noise amplifier assembly and the sum-difference modulator combination are fixed below the antenna bottom plate. The antenna bottom plate and the antenna cover are fixed on the antenna cavity. The lower end of the antenna cavity is provided with the cover plate. The input end of the filtering low-noise amplifier assembly is connected with the output end of the double-circular-polarization sub-array feed network. The output end of the filtering low-noise amplifier assembly is connected with the input end of the sum-difference modulator combination.

Description

technical field [0001] The invention relates to a wide-band double-circular polarization flat-panel self-tracking antenna, which belongs to the technical field of measurement and control products. Background technique [0002] The multi-target telemetry vehicle-mounted station is used for the telemetry and tracking tasks of multiple aircraft in different frequency bands on the ground at the same time. When the aircraft flies over the multi-target telemetry vehicle-mounted station, it realizes the real-time transmission of flight parameters and task load working state parameters, and tracks the aircraft. position. [0003] The multi-target telemetry vehicle-mounted station needs to carry out telemetry and tracking of multiple targets at the same time, requiring a vehicle to be equipped with multiple self-tracking antennas, which puts forward miniaturization requirements for the antenna. The antenna has the characteristics of a wide frequency band, and the efficiency of the a...
