Abstract

The invention provides an antenna system, which comprises a first antenna, a second antenna, a first signal source, a second signal source, a first isolation part and a grounding surface. The first antenna is connected with the first signal source and the grounding surface. The second antenna is connected with the second signal source and the grounding surface. A first gap is formed between the first antenna and the second antenna. The first isolation part, arranged between the first gap and the grounding surface, is connected with the grounding surface and is used for improving the isolationdegree between the first antenna and the second antenna. The antenna system is good in antenna isolation performance. The invention further provides a communication terminal.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to an antenna system and a communication terminal using the antenna system. Background technique [0002] In communication terminals such as mobile phones and tablet computers, the antenna component used to transmit and receive radio waves to transmit and exchange wireless communication signals is undoubtedly one of the most important components. With the popularity of the fourth-generation mobile communication technology, the mobile communication field has more and more urgent requirements for communication terminals with wide bandwidth and multiple antennas. At the same time, communication terminals represented by mobile phones are developing in the direction of thinner and lighter, which makes the available space inside the terminal limited. In recent years, the antenna system covering the global mobile communication frequency band has gradually become the standard ...
