Description:
Super Directive Huygens Antenna
Project ID: D2025-11
Background
The antenna industry has experienced substantial growth in recent years due to escalating
demands for high-speed connectivity and the proliferation of smart devices. Traditional patch
antennas, which are widely used because of their low profile and ease of fabrication, typically
achieve a gain of only about 2–3 dBi. A new super-directive patch antenna has been developed with gain exceeding 8dBi offering promising solutions for next-generation wireless technologies.
Invention Description
Researchers at the University of Toledo have developed a super-directive Huygens type patch antenna with gain over 8dBi.
Applications
Synthetic aperture radar, power beaming for UAVs, IoT, man-portable SATCOM, next-generation wireless communication.
Advantages
- Combined low profile of a patch antenna with high gain of a Huygens antenna
- Aperture efficiency of 120%
- Easily scalable to any frequency
- Front-to-Back Ratio of 12dB
- PCB compatible planar configuration
- Avoids complex fabrication of multi-element end-fire arrays
