Invention: [Technical Field of the Invention] The present invention is a mobile phone antenna device (m〇t) ile ph〇ne antenna device) which is particularly suitable for use in thinned mobile communication products. [Prior Art] = The rapid development of wireless communication, under the trend of light, thin, short and small products, the overall height of mobile communication products will affect the commercial value of a product. Therefore, thin mobile phones are also being continuously introduced. The antenna design types of such mobile communication products are mostly flat panel antennas, and the height of the conventional mobile phone panel antenna is about 7_1 mm, and the antenna below the radiating metal piece is connected. The ground plane and the ground plane are the same plane, so that the same side of the antenna = the inner section height is also about 7_10mm, and behind the grounding surface of the antenna system: the internal space needs to be placed into the glory, control panel and related circuit components. 'The overall height of the mobile phone is about 18 faces ^. For example, the patent of m#U_〇88, multi-frequency inverted F-type flat-panel antenna junction: Patent No. 54Π65 of the mouth of Bay, “Double-frequency inverted F-shaped panel antenna and 1308408 radiation metal sheet” and Taiwan Patent Publication No. 567641 Patented, dual-frequency inverted f-shaped planar antenna and radiant metal wire, both reveal a multi-frequency inverted-F-shaped planar antenna design. The height of the antenna radiating metal piece determines the height of the internal space on the same side of the antenna, so Without changing the height of the antenna, such an antenna design cannot be applied to a mobile communication device device that is thin (about 1 mm or less in mobile phone thickness). In addition to relying on the downsizing technology of antennas and other related circuit components, as well as the integration technology of RF modules, how to achieve more intensive integration of antennas with the above-mentioned two related objects, It is also a very important key factor to make the internal small space of mobile communication products more fully applicable. In order to solve this problem, we propose an innovation δ of a mobile phone antenna device, which can hide the antenna in a thin mobile communication product without changing the height of the antenna, and the original antenna height will not Become a decision: increase the height of the parameters, and make the space around the grounding surface of the system inside the device can be fully utilized. At the same time, we have also designed a dual-frequency operating antenna design suitable for the current mobile communication systems GSM (890-960 MHz) and DCS (1710-1880 MHz), and applied to the antenna device of the present invention to achieve a built-in type. The design of a thin dual-band mobile phone. SUMMARY OF THE INVENTION The present invention overcomes the shortcomings of the conventional mobile phone antenna device, which is not flexible, and proposes an innovative antenna device, which can be combined with the antenna design of a conventional mobile phone to achieve the goal of thinning the mobile phone. 1308408 Lu Jin Lifa: Includes: an antenna ground plane, - radiated metal sheet, - short one grounding ® money ground plane.

Antenna height (about 7_10m) m) consistent with the total height of the space occupied by the application components of the rear stage, so that the target of product thinning can be achieved without lowering the height of the antenna; in other words, the conventional antenna in the mobile phone antenna device The design can still meet the space limitation and achieve the bandwidth requirement required for the application. 1308408 [Embodiment] FIG. 1 is an embodiment of a mobile phone antenna device according to the present invention, including: an antenna ground plane 11 including: a sub-ground surface m having a substantially rectangular shape; and a second sub-ground surface 112 substantially perpendicular to the first sub-ground surface 111 and electrically connected to one side 113 of the first sub-ground surface lu The shape of the ground plane 1 大致 is substantially an L shape; a radiating metal piece Π is substantially surrounded by the ground plane u of the antenna, and is substantially parallel to the first sub-ground surface m of the antenna ground plane 11 and has a short circuit a point and a feed point 122 electrically connected to a feed signal source 123: a shorted metal element 13 having one end electrically connected to the radiating metal piece 12 and the other end electrically connected to the antenna ground plane n And a system ground plane 14 having a substantially rectangular shape, one side of which is electrically connected to the second sub-ground plane 112, and the system ground plane 14 is substantially parallel and extends away from the first sub-ground plane ill However, it is not in the same plane as the extended plane of the first sub-ground plane ui.
