Abstract

The invention provides an antenna structure and a communication terminal. The antenna structure comprises a first antenna radiator, a second antenna radiator, a first impedance matching circuit, a second impedance matching circuit and a signal source, The first antenna radiator and the second antenna radiator are coupled through a slot. One end, away from the gap, of the first antenna radiator isgrounded, and a feeding point is arranged on the first antenna radiator; one end, away from the gap, of the second antenna radiator is grounded, and the absolute value of the difference value of the length of the second antenna radiator and the 1 / 4 wavelength of the third frequency band is smaller than a first specific value. The first end of the first impedance matching circuit is connected withthe feed point, and the second end of the first impedance matching circuit is connected with the first end of the signal source. The first end of the second impedance matching circuit is connected with the third end of the first impedance matching circuit, and the second end of the second impedance matching circuit is grounded. The second end of the signal source is grounded. According to the embodiment of the invention, the voltage standing wave ratio of the antenna can be reduced, and the performance of the antenna is improved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an antenna structure and a communication terminal. Background technique [0002] With the rapid development of terminal technology, communication terminals have become an indispensable tool in people's lives, and have brought great convenience to all aspects of users' lives. Communication terminals with a metal middle frame or an all-metal battery cover that are common in daily life are generally equipped with antennas, and the antennas can work in multiple frequency bands, such as 1.55-1.62GHz, 2.4-2.5GHz and 5.15-5.85GHz work within the frequency range. [0003] However, in the prior art, the VSWR of the antenna is relatively large, resulting in relatively poor performance of the antenna. Contents of the invention [0004] Embodiments of the present invention provide an antenna structure and a communication terminal, so as to solve the problem of relatively poor anten...
