The invention discloses an antenna device for a mobile terminal. The antenna device is integrated on a printed circuit board (PCB) mainboard of the mobile terminal, and comprises a first ground plane component and at least one antenna feed component. The first ground plane component comprises at least one first ground plane part, a second ground plane part and at least one connecting piece, wherein one end of the connecting piece is connected with the first ground plane part, and the other end of the connecting piece is connected with the second ground plane part; and the at least one first ground plane part and the at least one connecting piece form one or more conductive annular loops. The at least one antenna feed component feeds to each conductive annular loop, and comprises an antenna feed piece and a feed connecting piece. The invention also discloses the mobile terminal and a feed method utilizing the antenna device. The antenna device is integrated on the PCB mainboard of the mobile terminal so as to achieve high radiation performance and increase the space utilization rate of the mobile terminal.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to an antenna device for a mobile terminal, a mobile terminal using the antenna device and a method for feeding power by using the antenna device. Background technique [0002] The current mobile terminal antennas are generally divided into two types: built-in type and external type. Among them, the built-in antenna is mainly in the form of Planar Inverted-F The polar antenna form is dominant. With the trend of light and thin appearance of mobile communication terminals, the working frequency band of 3G / 4G continues to increase, and the previous built-in antenna design has been severely challenged, but the design method of simply reducing the size of the built-in antenna and saving the space of the mobile terminal It will make the signal of the mobile terminal unstable and affect the user experience. [0003] The design of the built-in antenna generally requires a s...
