AI Technical Summary

Technical Problem

Existing antenna configurations for full-duplex transmission suffer from high electromagnetic attenuation and crosstalk between transmitting and receiving channels, particularly in devices rotating relative to each other, limiting data transmission capabilities and preventing simultaneous use of multiple transmission protocols.

Method used

An antenna arrangement with multiple antennas surrounding a common central axis, oriented to minimize crosstalk through equal distances and orthogonal signal lines, and polarization alignment, allowing simultaneous transmission and reception of electromagnetic waves.

Benefits of technology

The solution effectively compensates for crosstalk, enabling high-quality, simultaneous bidirectional data transmission across rotating devices, supporting various transmission protocols, and replacing conventional connectors.
