Abstract
Official abstract text for this publication.
An antenna structure includes a substrate and a plurality of radiation units, each radiation unit comprising a first radiator and a second radiator. The first radiator is positioned on a first surface of the substrate and includes a first radiation portion and a feed point. The feed point is electrically connected to the first radiation portion for feed current and signals to a corresponding radiation unit. The second radiator is positioned at a second surface of the substrate and is symmetrical with the first radiator about the substrate. The second radiator includes a second radiation portion and a ground portion. The ground portion is electrically connected to the second radiation portion to provide grounding for the radiation unit. The antenna structure has a good radiation efficiency and good isolation between radiators to reduce cross-interference.
First claim
