The utility model relates to a coupled feeding inverted F-antenna. The coupled feeding inverted F-antenna comprises a bottom plate, an insulating cover and an antenna body. The antenna body is sealed and packaged on the bottom plate via the insulating cover, and the antenna body comprises a left radiator and a right radiator. The left and right radiators are arranged back to each other and symmetrically, the outer side edge of the left radiator supports on the bottom plate in an insulating manner, and a coupled feeding sheet supported by a feed rod is arranged under the middle part of the left radiator. The coupled feeding sheet is in parallel coupling arrangement with the left radiator, the feed rod is connected with a feed interface under the bottom plate, and the inner side edge of the left radiator supports on the bottom plate via a grounding column and penetrates the bottom plate to be grounded outwards. The outer side edge of the right radiator supports on the bottom plate in the insulating manner, a coupling grounding sheet supported by a grounding rod is arranged under the middle part of the right radiator and is in parallel coupling arrangement with the right radiator. The grounding rod is connected with a grounding interface under the bottom plate, and the inner side edge of the right radiator supports on the floor via the grounding column.
