The invention relates to a feed-in structure of an antenna, which comprises a baseplate, a first radiation unit, an insulation unit, a first feed-in point, a first ax-shaped grounding unit, a first gap and a second feed-in point, wherein the baseplate comprises a first surface and a second surface; the first radiation unit and the insulation unit are laid on the first surface, and the first radiation unit is arranged between the baseplate and the insulation unit; the first feed-in point is formed on the second surface and electrically connected with the first radiation unit after penetrating through the baseplate; the first ax-shaped grounding unit and the first radiation unit are coplanar, and one end of the first ax-shaped grounding unit is electrically connected with the first radiation unit; the first gap is formed between the first radiation unit and the first ax-shaped grounding unit; the second feed-in point is formed on the second surface and electrically connected with the first ax-shaped grounding unit after penetrating through the baseplate; and the second surface of the baseplate is close to at least one metal part and assembly. The radiation unit can not directly face to a battery module or other metal parts and assemblies of an electronic device, thereby reducing the opportunity of obstructing and disturbing the radiation unit to receive and send signals by a metal; in addition, the ax-shaped grounding unit is also utilized by the feed-in structure to increase the operation bandwidth.
Description
technical field [0001] The present invention relates to an antenna feeding structure, especially an antenna structure in which the feeding point forms the second surface of the substrate and the antenna radiator is on the first surface of the substrate. Background technique [0002] Due to the miniaturization of electronic devices today, the internal space of the electronic device casing is narrow, so the antenna will be close to large metal parts such as batteries, motherboards, and LCD panels, and it is easy to form a metal shield that interferes with the signal reception of the antenna. In the past, the feed point of the antenna and the radiator are located on the same plane, which is easily interfered by the surrounding metal parts, resulting in poor signal reception of the antenna, and the current antenna generally adopts the design of an L-shaped grounding unit, and its operating bandwidth will be reduced. restricted. [0003] Therefore, how to develop a feed-in struc...
