Title: ANTENNA AND MOBILE TERMINAL
Abstract:
The present utility model relates to the field of communications. Disclosed are an antenna and mobile terminal, the antenna comprising a ground wire and a feed wire; the feed wire comprises a low frequency branch and a high frequency branch; the low frequency branch and the high frequency branch have a common end point; the low frequency branch is surrounded by the ground wire to form a coupled loading mode and an equivalent coupled feed loop antenna radiation mode; and the high frequency branch is disposed outside the ground wire to complete a high frequency monopole radiation mode. The mobile terminal comprises a PCB board and an antenna; the antenna is printed on the PCB board. An embodiment of the present utility model solves the problem of insufficient low frequency bandwidth and high frequency bandwidth in the prior art, effectively improves antenna performance, and can effectively disperse near-field energy to the PCB and the mobile terminal, thus reducing SAR, saving cost, and increasing the effective distance from the antenna to an SAR test instrument trunk model.
