Mobile devices and antenna structures

Abstract

Mobile device and antenna structure. The mobile device includes a metal mechanical component, a dielectric substrate, a support element, a feeding radiation part, a ground plane, a short circuit part, a circuit element, a first and a second parasitic radiation part, and an additional radiation part; the metal mechanical component has a first and a second a slot at the closed end; the dielectric substrate has opposite first and second surfaces; the supporting element is disposed on the metal mechanical component and supports the dielectric substrate; the ground plane and the short circuit part are respectively coupled to the metal mechanical component; the circuit element is coupled to the short circuit part and the first ground point of the ground plane; the first and second parasitic radiation parts are respectively coupled to the ground plane; the additional radiation part is adjacent to or coupled to the feeding radiation part, the first and second parasitic radiation parts, the additional The radiating part is arranged on the first surface of the dielectric substrate; the feed-in radiating part, the circuit element, the first and second parasitic radiating part, the additional radiating part, and the slot holes of the metal mechanical component jointly form an antenna structure. The invention has the advantages of small size, wide frequency band, beautiful appearance and the like.

Description

technical field [0001] The present invention relates to a mobile device (Mobile Device), in particular to a mobile device and its antenna structure (Antenna Structure). Background technique [0002] With the development of mobile communication technology, mobile devices have become more and more common in recent years, such as portable computers, mobile phones, multimedia players and other portable electronic devices with mixed functions. In order to meet people's needs, mobile devices generally have a wireless communication function. Some cover long-distance wireless communication ranges, for example: mobile phones use 2G, 3G, LTE (Long Term Evolution) systems and their frequency bands of 700MHz, 850MHz, 900MHz, 1800MHz, 1900MHz, 2100MHz, 2300MHz and 2500MHz for communication, while Some cover short-range wireless communication ranges, for example: Wi-Fi, Bluetooth systems use 2.4GHz, 5.2GHz and 5.8GHz frequency bands for communication. [0003] In order to pursue beautif...
