An Isolation Enhancement Technique for the Dual-Polarized Probe-fed Patch Antenna 用于双极化探針饋电貼片天綫的隔離增强技術

IP Title

Summary

The dual-polarized patch antennas designed by CityU are compatible with L-shaped probes, which are also invented by CityU. The L-shaped probe is connected to the input port, and part of it is parallel to the patch. The isolation enhancement technique inherent in this invention can reduce the strong coupling between the feeding probes of different polarizations within each array element and between different array elements. As a result, a high input port isolation can be achieved over a wide range of frequencies.

Technology Application

• For use in the base stations of wireless communication systems to reduce multi-path fading at the receiving antennas
