Multi-Patch Antenna Feed Layout for UWB Polarization Alignment

Solution Overview

Problem

In UWB communication, the directions of linearly polarized waves and circularly polarized waves generated from multiple conductive patches can differ, leading to deteriorated communication performance due to mismatched wave directions.

Innovation Solution

An electronic device is designed with a plurality of conductive patches, where a wireless communication circuit feeds power to specific points on each patch to align the directions of linearly polarized waves and circularly polarized waves, ensuring they are generated in the same direction, using a configuration where patches are oriented to have identical shapes and are spaced apart along specific axes, with the wireless communication circuit positioned to minimize signal loss and maximize alignment.
