With the development of mobile communication technology, mobile devices are becoming increasingly popular in recent years, and common examples are: portable computers, mobile phones, multimedia players, and other portable electronic devices with mixed functionality. To meet the needs of people, mobile devices often have wireless communication capabilities. Some cover long range wireless communication ranges, such as: mobile phones use 2G, 3G, LTE (Long Term Evolution) systems and the frequency bands of 700MHz, 850MHz, 900MHz, 1800MHz, 1900MHz, 2100MHz, 2300MHz, and 2500MHz for communication, while some cover short range wireless communication ranges, such as: wi-Fi, bluetooth systems use the frequency bands of 2.4GHz, 5.2GHz, and 5.8GHz for communication.

In order to pursue a beautiful appearance, designers nowadays often add elements of metal elements to mobile devices. However, the added metal elements tend to negatively affect the antenna supporting wireless communication in the mobile device, thereby reducing the overall communication quality of the mobile device. Therefore, there is a need for a new mobile device and antenna structure to overcome the problems of the conventional technology.
