MULTI-BAND ANTENNAS USING MULTIPLE PARASITIC COUPLING ELEMENTS AND WIRELESS DEVICES USING THE SAME

摘要

A multi-band antenna includes a ground plane, a branch active element connected to the ground plane, and a plurality of parasitic coupling elements connected to the ground plane. Respective ones of the parasitic coupling elements are electrically coupled to the branch active element such that the multi-band antenna resonates at a plurality of frequency bands.
