A dual-band antenna comprises a substrate, a first radiator, and a second radiator. The first radiator is located on the top surface of the substrate and comprises a plurality of first sub radiators. Each of the first sub radiators comprises a first feed-in part, a first resonating 5 part, and a second resonating part. The second radiator is located on the bottom surface of the substrate and comprises a plurality of second sub radiators. Each of the second sub radiators comprises a second feed-in part and a third resonating part. The third resonating part is coupled with the second feed-in part and its projection partially overlaps with a projection of the first resonating part of one of the first sub radiators and another projection 10 of the second resonating part of one of the first sub radiators. - e~ o c'~ - ~ 'I - c/1c/1e'~ (NI |
