Abstract

The invention discloses a multi-band antenna device and a hand-held terminal with the same. The multi-band antenna device comprises a metal mainboard and an antenna body which is connected with the metal mainboard. The antenna body comprises a first antenna branch and a second antenna branch, one end of the first antenna branch is connected with the feed end of the metal mainboard, and the other end of the first antenna branch is connected with a first switch. One end of the first switch is in switching connection with the second antenna branch and the ground end of the metal mainboard, and the second antenna branch is connected with the ground end of the metal mainboard through at least one second switch. The first switch and the second switch are used, so that at least two annular antenna loops are ingeniously achieved on the same antenna body, the purpose that the single antenna body works for multiple bands in a switching mode is achieved, the space occupied by the multi-band antenna device is greatly lowered, and the weakening degree to the antenna performance can be greatly lowered when a human hand touches a metal decorative piece.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, and more specifically, relates to a multi-band antenna device and a handheld terminal provided with the multi-band antenna device. Background technique [0002] As users' demand for the appearance and texture of the whole machine increases, it is the development trend of the hand-held terminal industry to add metal and metal decorations to the whole machine of the hand-held terminal (such as a mobile phone). However, because metal has a shielding effect on the antenna, the metal The effect on the antenna is very large. In the case of ensuring that the thickness of the whole machine meets the ultra-thin requirements, existing technologies, such as Apple's slits on the metal ring, use metal as the radiator of the antenna. However, due to the influence of manual contact, this kind of antenna device is likely to cause poor actual use effect by users; moreover, this kind of anten...
