Abstract

An antenna system comprises a feed terminal, a first matching circuit, a first radiator, a second radiator, a first changeover switch, a second changeover switch, a third changeover switch and a first groun terminal, wherein the feed terminal is spaced with the first ground terminal, the first radiator comprises a first end and a second end that are opposite to each other, wherein the first end is electrically connected with the feed terminal through the first matching circuit, the second radiator is arranged on one side of the first radiator and is spaced with the first radiator to form a gap, the second radiator is connected with the first radiator at the first end through the first changeover switch and is connected with the first radiator at the second end through the second changeover switch, and the second radiator is connected with the first ground terminal through the third changeover switch. The antenna system has a relatively wide frequency band range. The present invention further provides a communication terminal.

Description

technical field [0001] The 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 smartphones 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 smart phones are developing in the direction of thinner and thinner, which makes the available space inside the terminal limited. How to design an antenna with wide bandwidth and better radiation characteristics in a limited space is an important issue in the field of...
