Abstract

The present invention relates to the field of communication technology, and discloses a wireless mobile device, which includes a metal frame and a circuit board arranged in the metal frame. There is a gap between at least one side of the circuit board and the metal frame, and a first grounding point is connected to the circuit board and Metal frame connection, the second ground point is connected to the circuit board and the metal frame, the feed point is located between the first ground point and the second ground point, and is connected to the circuit board and the metal frame; each antenna open-circuit branch is suspended on the circuit board The outer space and one end are connected to the metal frame across the gap, and the connection point between the antenna open branch and the metal frame is located between the feeding point and the second grounding point. In the above-mentioned wireless mobile device, antennas of multiple frequency bands form resonance through the gap between the circuit board and the metal frame, and the radiation efficiency of the antenna will not be affected by the metal frame. Therefore, the slot antenna in the above-mentioned wireless mobile device is within the required frequency band The radiation power is relatively high, and the antenna structure is compact.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a wireless mobile device. Background technique [0002] In the field of communication technology, wireless mobile devices have advantages such as portability. Especially for mobile devices such as mobile phones, in order to pursue a more beautiful appearance, in addition to the compact size of the whole machine, more and more metal parts are applied to the design of wireless mobile devices. [0003] However, in the wireless mobile device, the introduction of metal components will greatly affect the performance of the antenna in the wireless mobile device while increasing the appearance of the wireless mobile device. [0004] Such as figure 1 as shown, figure 1 A schematic structural diagram of an antenna provided for a mobile phone in the prior art. figure 1 The mobile phone shown includes a metal frame 01, a circuit board 02 inside the metal frame 01, and a gap 012 is...
