Embodiment 1

[0030] Such as figure 1As shown, a highly integrated series-fed circular polarization correction network includes: 8 circular polarization correction network units 1, 2 correction connectors 15, 1 coupled stripline 14; 8 circular polarization correction The network units are arranged at equal intervals along the same direction and linearly in the manner of traveling wave series feeding to form a long rectangular dielectric plate, and the coupling stripline 14 is etched inside the long rectangular dielectric plate along the length direction of the long rectangular dielectric plate. Both ends of the coupling stripline 14 are respectively connected with calibration connectors 15; along both sides of the coupling stripline 14 and the long side of the long rectangular dielectric plate, a plurality of metallized holes are opened. In order to avoid a larger reflection coefficient superposition singular point in the band, the distance between the eight circular polarization correction...

Abstract

The invention discloses a high-integration-level series-fed circular polarization correction network and a working method thereof, belongs to the technical field of phased-array antennas, and solves the problem that a traditional series-fed correction network does not have a circular polarization forming function and is not suitable for a circular polarization phased-array antenna system. According to the technical scheme, three-dimensional integration of the correction network and the circularly polarized bridge is achieved structurally, so the number of connectors and cable assemblies is reduced, feed line loss is reduced, the size, weight and cost are reduced, and the reliability is improved; dual circular polarization radiation and series feed correction of the antenna are simultaneously realized in function; a circular polarization bridge is embedded in the rectangular hollow part of the correction dielectric plate, so that the design of separating the circular polarization bridge from the correction coupler is realized, any circular polarization bridge can be independently replaced, and the maintainability is improved; the coupling degree is controllable, and the purpose of regulating and controlling the coupling degree is achieved by adjusting the size of the inclined coupling hole; and a coupling strip line structure is adopted, so that external interference is effectively isolated.

Description

technical field [0001] The invention belongs to the technical field of phased array antennas, and in particular relates to a highly integrated series-fed circular polarization correction network and a working method thereof. Background technique [0002] In order to prevent the polarization mismatch loss caused by the Faraday rotation effect when the electromagnetic wave penetrates the ionosphere, the antenna is required to have circular polarization performance, and the same antenna array works simultaneously in the receiving mode and the transmitting mode, which requires the antenna to have dual Circular polarization capability. [0003] Due to various reasons such as device inconsistency, manufacturing tolerances, and assembly tolerances, the phased array antenna system must have initial amplitude and phase errors in each channel, so the phased array antenna system must be corrected, that is, the initial amplitude and phase of each channel must be corrected. The characte...
