Problems solved by technology

The current mobile phone antenna design trend is to use a single antenna to achieve multi-band operation, but antenna designers often find that when adjusting the performance of the LTE frequency band, it will destroy the performance of the 2G / 3G frequency band. due to coupling characteristics

Abstract

The invention discloses a mobile device, comprising: a system circuit board, a grounding element, a communication module, a first antenna, a second antenna, a first antenna switching module, and a second antenna switching module. The first antenna is used for receiving or transmitting a first signal in a first frequency band. The second antenna is used for receiving or transmitting a second signal in a second frequency band. The second frequency band is different from the first frequency band. The first antenna switching module is coupled between the communication module and the first antenna, and is used for separating the frequency of the first signal. The second antenna switching module is coupled between the communication module and the second antenna, and is used for separating the frequency of the second signal. The mobile device of the present invention can cover a wider frequency band by adopting the dual antenna system.

Description

technical field [0001] The present invention relates to a mobile device, and more particularly to a mobile device comprising dual antennas. Background technique [0002] With the vigorous development of the mobile communication device market, various mobile communication products have been launched in the market one after another. Judging from the current trend, they can be roughly divided into three major categories: smart phones, tablet PCs and notebook computers. class products. In order to pursue faster networking speed and high-quality network audio and video transmission, the fourth-generation mobile communication technology LTE (Long Term Evolution, long-term evolution technology) is being rapidly commercialized. The frequency band of LTE ranges from low frequency 700MHz to high frequency 2690MHz, probably more than 10 application frequency bands. Since the LTE communication system is different from the traditional 2G / 3G communication system, it needs to match diffe...
