AI Technical Summary

Technical Problem

The existing antenna design is difficult to support multi-band communication at the same time, resulting in complex structures and large space occupancy, and it is difficult to meet the bidirectional communication needs of Beidou satellite reception and transmission frequency bands.

Method used

An antenna structure is designed, including a first feed source, a second feed source, a first antenna and a second antenna. The first antenna supports the Beidou satellite reception frequency band and the second antenna supports the Beidou satellite transmission frequency band, and miniaturization and lightweight are achieved through a shared partial structure.

Benefits of technology

It realizes simultaneous coverage of the Beidou satellite reception and transmission frequency bands, supports two-way communication, improves structural integration and usage efficiency, and reduces the size and space of the antenna.
