AI Technical Summary

Technical Problem

The existing miniaturized large S antennas have insufficient volume and weight, and cannot meet the requirements of higher bandwidth, higher gain, smaller body shape and lighter weight.

Method used

The power-feeding network PCB board and radiation unit are used to uniformly set up the thimble, two high-frequency boards with the same structure are superimposed, and bridge connection and installation holes are set on the power-feeding network PCB board, and the signal lines are distributed in a vertical feed manner.

Benefits of technology

It realizes the small size and light weight of the antenna, and improves bandwidth and gain, and has the characteristics of good circular polarization.

Abstract

The utility model discloses a miniaturized large S antenna, which belongs to the technical field of satellite communication antennas, and comprises a feed network PCB (printed circuit board) and a radiation unit, four thimbles are uniformly arranged between the radiation unit and the feed network PCB, the radiation unit comprises two high-frequency boards with the same structure, a plurality of via holes are arranged between the high-frequency boards, and the thimbles are arranged on the feed network PCB. One side of the feed network PCB is fixedly connected with a signal line. According to the utility model, through cooperative use of the radiation unit, the signal line and other components, the overall weight can be effectively reduced, the overall size is reduced, and the antenna is convenient to use.
