Abstract

The invention relates to an S-band dual-circular-polarization high-integration broadband phased array subarray antenna, and belongs to the technical field of communication. The antenna comprises an independent radiation layer and a multi-layer microstrip patch antenna; the PCB 4 of the independent radiation layer is a Tacic single-sided core board; the multi-layer microstrip patch antenna is formed by mixing and pressing a single-face core board PCB 1, a single-face core board PCB 2 and a double-face core board PCB 3 through prepregs, so as to form a feed network strip line model. Taconic single-face core boards are adopted as the single-face core board PCB 1 and single-face core board PCB 2 of the multi-layer microstrip patch antenna, and a Taconic double-face core board is adopted as the double-face core board PCB 3; the independent radiation layer and the multi-layer microstrip patch antenna are fastened through a metal stud. The antenna has the advantages of being high in isolation degree, wide in working bandwidth, good in circular polarization characteristic and excellent in voltage standing wave ratio, and meanwhile the antenna has the advantages of being low in profile, simple in structure, easy to machine and the like.

Description

technical field [0001] The invention belongs to the technical field of communication, and relates to an S-band double-circular polarization high-integration broadband phased array sub-array antenna. Background technique [0002] At present, aerospace measurement and control has gradually developed from a traditional single-beam, single-target measurement and control system to a multi-beam, multi-target measurement and control system. However, the traditional single ground measurement and control station using parabolic antennas can no longer meet the requirements of simultaneous multi-target measurement and control tasks. The phased array antenna plus digital beamforming (DBF) architecture can achieve simultaneous multi-target measurement and control. The single station of this architecture can not only realize the measurement and control of more than a dozen targets arbitrarily distributed in the whole airspace, but also can adapt to the development trend of future measurem...
