AI Technical Summary

Technical Problem

Existing patch array antenna systems face challenges in maintaining substantially equal gain values in multiple directions during beamforming operations, particularly when adjusting the main lobe direction, due to the limitations of planar substrates.

Method used

The antenna system employs a first substrate with a curved surface configuration relative to a second substrate, allowing antenna elements to be disposed on a curved surface, and incorporates a control device to adjust the radiation pattern, ensuring equal gain in any direction through beamforming operations.

Benefits of technology

This configuration enables approximately equal gain in any direction, enhancing signal strength and reducing manufacturing and implementation costs for 5G networks by simplifying the process and improving data rates and latency.

Abstract

According to an exemplary embodiment of the present invention, an antenna system may include a first substrate, which may include an antenna array having a plurality of antenna elements. The antenna system may further include a second substrate spaced apart from the first substrate and may include radio frequency circuitry operable to carry radio frequency signals communicating via the antenna array. The first substrate may have a curved surface configuration relative to the second substrate, such that at least one of the plurality of antenna elements can be disposed on the curved surface of the first substrate.
