Abstract

The invention discloses a Q / V frequency band low orbit satellite tile type phased array receiving standard subarray. The subarray comprises an antenna housing, an antenna array surface, a tile type phased array receiving module, a synthetic network and a shell, the antenna housing is made of an electromagnetic metamaterial capable of effectively improving the large-angle scanning circular polarization axial ratio; the antenna array surface comprises a plurality of antenna units; the tile type phased array receiving module takes a multi-channel multifunctional chip as a main body, and amplification, phase shift and attenuation functions are integrated in the chip. The modular multi-beam phased array antenna has the characteristics of flexible beam switching, simultaneous multi-beam and large-angle scanning, low circular polarization axial ratio, high integration level and reliability and modularization, can be freely spliced, and provides convenience for constructing phased arrays of any scale.

Description

Technical field [0001] The present invention belongs to the field of satellite communication, and it is related to a Q / V band low-run satellite tile-type phase-controlled array receiving standard sub-array. Background technique [0002] With the rapid development of satellite communications, the phased range is more and more widely used in the advantages of multi-beam, fast tracking scans and high reliability. At present, the international commercial communication satellite communication load has gradually developed a higher frequency KA band on the basis of continuing use of traditional C and KU bands. It is foreseeable that future commercial satellite bandwidth resources will continue to grow, and the resources of the KA band will be increasingly crowded. As the demand for communication is continuously improved, the amount of data transmission is increasing to the bandwidth, and the communication load technology of the Q / V band is imminent. [0003] In practical application...
