AI Technical Summary
Technical Problem
Existing dual-frequency resonant antennas have complex structures and are not integrated designs, resulting in high production costs.
Method used
The resonant antenna structure adopts an integrated design, including a substrate, a resonator, a ground plane, and a feed line. The resonator consists of first and second resonant units, with the second resonant unit located at the edge of the first resonant unit. The ground plane and the feed line are located on the surface of the substrate, simplifying the structure.
Benefits of technology
This achievement enables dual-band coverage of the 28GHz and 39GHz frequency bands for a single resonant antenna, reducing production costs and improving radiation efficiency.
