Embodiment Construction

[0036] In order to make the purpose, features and advantages of the present invention more comprehensible, specific embodiments of the present invention are listed below and described in detail with accompanying drawings.

[0037] figure 1 It is a schematic diagram showing the mobile device 100 according to an embodiment of the present invention. The mobile device 100 can be a smart phone (Smart Phone) or a tablet computer (Tablet Computer). Such as figure 1 As shown, the mobile device 100 includes: a dielectric substrate 110 , a ground plane 120 , an adjustable antenna 130 , and a switch 170 . The dielectric substrate 110 can be a system circuit board, an FR4 substrate, or a flexible printed circuit board (FPCB). The ground plane 120 and the adjustable antenna 130 can be disposed on the dielectric substrate 110 . The adjustable antenna 130 is disposed adjacent to the ground plane 120 . Both the ground plane 120 and the adjustable antenna 130 can be made of metal, such as...

Abstract

The invention discloses a mobile device which comprises a media substrate, a grounding face, an adjustable antenna and a switcher. The adjustable antenna comprises a feed-in part, a first parasitic part and a second parasitic part. The feed-in part comprises a first section and a second section. A signal source is coupled to the joint of the first section and the second section. A first coupling gap is formed between the first section and the first parasitic part of the feed-in part. A second coupling gap is formed between the second section and the second parasitic part of the feed-in part. The switcher selectively couples the first parasitic part or the second parasitic part to the ground. The mobile device provided by the invention can switch between different parasitic parts of the adjustable antenna according to the display mode, so that the adjustable antenna can maintain a required radiation field pattern.

Description

technical field [0001] The invention relates to a mobile device, in particular to a mobile device and an adjustable antenna thereof. Background technique [0002] At present, the global positioning system (Global Positioning System, GPS) has been listed as one of the basic functions of the smart phone, and the quality of the GPS antenna plays a decisive role in the GPS reception performance of the mobile phone. Early feature phones mostly used circularly polarized ceramic antennas as GPS antennas. However, since the internal space of current smart phones is not enough to place the above-mentioned circularly polarized ceramic antennas, they are almost always replaced by general linearly polarized antennas. [0003] In order to increase the speed of mobile phone and satellite positioning, when designing the GPS antenna, it will try to make the radiation pattern of the antenna face the sky, so as to receive signals easily. Most of the smart phones will set the GPS antenna on t...
