AI Technical Summary

Technical Problem

Existing technologies make it difficult to cover multiple cellular or Wi-Fi bands on small-sized antenna radiators, resulting in insufficient space for other antenna layouts and limited design freedom.

Method used

Design an antenna assembly that introduces a first radiating stub, a second radiating stub, and a first equivalent resonant circuit on the same antenna radiator, generates multiple resonant modes using a first feed system, and sets the resonant frequency of the first equivalent resonant circuit to be lower than the center frequency of the second frequency band and higher than the center frequency of the first frequency band, so as to support resonance in more frequency bands.

Benefits of technology

It achieves efficient radiation covering a large frequency band simultaneously on the same antenna radiator, saving space and increasing design freedom, meeting the requirements of multiple standards without the need for additional switching switches, and reducing the cost of radio frequency systems.
