AI Technical Summary

⚠Technical Problem

Currently, base station antennas are difficult to configure with any different operating frequency bands according to different usage requirements, resulting in poor applicability.

⚗Method used

Design an antenna system including a first feed module, a second feed module, a first radiator, and a metasurface radiator. Multi-frequency communication is achieved through indirect coupling. The structure and gaps of the conductive elements in the metasurface radiator adjust the propagation characteristics. The operating frequency and bandwidth are adjusted by combining the structure and gaps of the conductive elements. The metasurface radiator is set to be thin to achieve low-profile broadband characteristics. The frequency band can be adjusted by conveniently replacing or adding independent feed modules.

🎯Benefits of technology

It enables multi-frequency or dual-frequency operation of the antenna system, expands the bandwidth, reduces the design difficulty of metasurface radiators, improves the applicability and flexibility, and simplifies the installation complexity.

Abstract

The present application provides an antenna system, a communication device, and a communication system. The antenna system comprises a first feed module, a second feed module, a first radiator, and a metasurface radiator. The second feed module and the metasurface radiator are arranged opposite to each other in a first direction. The second feed module is indirectly coupled to the metasurface radiator and is used for exciting the metasurface radiator to radiate electromagnetic waves in a second frequency band. The first feed module is used for exciting the first radiator to radiate electromagnetic waves in a first frequency band. The first radiator and the first feed module are arranged between the second feed module and the metasurface radiator in the first direction, and the metasurface radiator transmits electromagnetic waves in the first frequency band. The first direction is the thickness direction of the metasurface radiator. The second feed module and the metasurface radiator are configured as two independent modules. The antenna system can be conveniently and flexibly configured, expanding application scenarios of the antenna system.
