ナ。[Claims for Utility Model Registration] 1. Copper is provided by vapor deposition or adhesion on a base film constituting a thin plate-like insulating substrate, and on the copper foil, a relatively long horizontal pattern portion of an antenna element and its An inverted F-shape consisting of a vertical and short antenna element grounding pattern section at one end, and a vertical and short antenna element feeding pattern section between one end of the antenna element horizontal pattern section and the other end, the end point, and the antenna. A pattern mask is placed at the end of the element ground pattern section to form a ground plate that is a relatively wide band-shaped ground substrate parallel to the antenna element horizontal pattern section, and then photo etched. An inverted F-print antenna integrated with a ground plate, which is characterized in that the excess portion is removed, a cover film is placed on top of it, a feeding point is provided in the antenna element feeding pattern, and the ground plate is grounded. 2 The antenna element ground pattern extends vertically from one end of the antenna element horizontal pattern by the same length, and is integrated with the terminals of the element ground pattern of both antennas, parallel to the antenna element horizontal pattern, and relatively wide in width. After arranging the pattern mask to form both base plates that form a strip-shaped ground board, remove the excess by photo etching, and then wrap a cover film over it to feed power to the antenna element power feed pattern. 2. The ground plate integrated inverted F printed antenna according to claim 1, wherein the ground plate is grounded. 3 Copper foil is provided by vapor deposition or adhesion of copper on both the front and back surfaces of the base film, which forms a thin plate-like insulating substrate, and the antenna element and A loading coil is formed in a printed form, and a loading coil is formed in a printed form on the coating on the back side of the copper foil, and a through foil is punched through both the front and back sides of the insulating substrate. The ground plate integrated inverted F printed antenna according to claim 1, wherein both loading coils formed on the front and back surfaces are connected.
