In the case of this chemical formula, please disclose the ninth indication of the medical certificate. The invention description: • The technical field] d. Shuming is a mobile phone antenna device (see ph_ant_e gene) is particularly suitable for thin-shaped mobile communication products. [Prior Art] With the rapid development of wireless communication, the overall height of mobile communication products will affect the commercial value of a product ° under the trend of light, thin, short and small products. Therefore, thin mobile phones are also constantly being introduced. Most of the antenna design types of such mobile communication products are mainly flat panel antennas, and the height of the conventional dual-frequency mobile phone flat panel antenna is about 7_10 mm, and the antenna below the radiating metal piece is connected. The ground plane and the system ground plane are in the same plane, so that the inner section height on the same side of the antenna is also about 7-l〇mm, and the internal space behind the grounding surface of the antenna system needs to be placed on the screen, the control panel and related circuits. The overall height of the mobile phone is about 18mm. For example, the patent of Taiwan Patent Publication No. M284088 "Multi-frequency inverted F-type flat-panel antenna structure" Taiwan Patent No. 541765 patent "Double-frequency inverted F-shaped panel antenna and 7 200803036 light-emitting metal sheet" and Taiwan Patent Publication No. 567641 patent, , dual-frequency inverted f-shaped flat-panel antenna and radiant metal wire", both reveal a multi-frequency heart-shaped flat-panel antenna design, the height of the antenna radiating metal piece determines the height of the interior of the same side of the antenna to 1 height, so no In the case of changing the height of the antenna, such antenna design cannot be applied to a mobile device with a thin shape (about 1Gmm or less of mobile phone thickness), and the reduction of mobile communication products depends on the antenna and other phases. In addition to the integration technology of the road components and the integration technology of the (four) group, it is also very important to integrate the above-mentioned objects of Tianze with more intensive integration, so that the narrow space inside the mobile communication products can be more fully applied. Key factors. To solve this problem, we propose a mobile phone antenna device: design, without changing the height of the antenna In the mobile communication product in which the antenna is built in the shape of the 溥, the original antenna height will not become the parameter of increasing the height and make the space around the grounding surface of the system in the device fully utilized. A two-frequency operating antenna design suitable for the current line=communication system GSM (890-960 MHz) and DCS (171〇_188 bribe 2) is also designed and applied in the antenna device of the present invention. The invention discloses that the conventional mobile phone antenna device does not have an 'innovative antenna device' and can be combined with the antenna design of the conventional mobile machine. The invention aims to achieve a thinning of the mobile phone. The invention includes: an antenna ground plane, a radiating metal piece, a short-circuited metal component and a system grounding surface, wherein the antenna grounding surface comprises: a first sub-grounding surface, a shape a substantially rectangular shape; and a second sub-ground surface substantially perpendicular to the first sub-ground surface and electrically connected to one side of the first sub-ground surface to make the antenna ground plane The shape is substantially an L shape; the radiation is attached to the sub-frame, substantially surrounded by the ground plane of the a-antenna antenna, and is substantially parallel to the first sub-ground plane of the ground plane of the antenna, and has a short-circuit point and a feed point. The feed point is electrically connected to a feed signal source; the shorted metal component has one end electrically connected to the radiating metal piece and the other end electrically connected to the antenna ground plane; the system ground plane is substantially rectangular in shape. One side of the bean is electrically connected to the second sub-ground surface, and the system ground plane is substantially parallel and extends away from the first sub-ground plane, but is not in the same plane as the extended plane of the first sub-ground plane.
