Abstract:
The present application relates to an antenna module, a positioning system, and an electronic device. The antenna module comprises: a dielectric substrate having a first surface and a second surface that are arranged facing away from each other; a grounding plate which is arranged on the first surface of the dielectric substrate; a radiation patch which is arranged on the second surface of the dielectric substrate, the radiation patch being provided with a feed point and a plurality of grounding points, and the plurality of grounding points being respectively arranged on the two sides of the feed point in a first direction; and a plurality of grounding structures, the grounding structures passing through the dielectric substrate so as to connect the grounding plate and the corresponding grounding points. By arranging the grounding points located on the two sides of the feed point respectively, the flow directions of surface currents of the radiation patch can be changed, thus making the surface currents at least partially cancel each other out in a second direction, the second direction being perpendicular to the first direction.
