摘要
A near field magnetic coupling antenna may include a plurality of annularly arranged radiators and an annular conductive portion. The annular conductive portion may include a plurality of conductive segments. A first gap may be formed between any two adjacent radiators. Each conductive segment may partially overlap two adjacent radiators and any two adjacent conductive segments may be separated by a second gap. Two adjacent radiators may be associated with a feed point and a ground point, respectively, and the feed point and the ground point may be disposed in the proximity of the first gap.
