Antenna Unit and Electronic Device - A simplified explanation of the abstract
This abstract first appeared for US patent application 17920570 titled 'Antenna Unit and Electronic Device
Simplified Explanation
The patent application describes an antenna unit and electronic device that use two feeds to excite signals at different ports of a loop antenna. The antenna unit is designed to be electrically symmetric, allowing for self-cancellation of signals between the ports and implementation of signal isolation and interference self-cancelation. The signals at the two ports can complement each other in different radiation directions, resulting in two antennas with high isolation and a low envelope correlation coefficient (ECC) based on the same loop antenna.
