The present invention provides an antenna structure and a communication terminal. The antenna structure includes: 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 The two antenna radiators are coupled through a slot, the end of the first antenna radiator away from the slot is grounded, the first antenna radiator is provided with a feed point, the end of the second antenna radiator away from the slot is grounded, and the end of the second antenna radiator is grounded away from the slot. The absolute value of the difference between the length and the 1 / 4 wavelength of the third frequency band is less than the first specific value; the first end of the first impedance matching circuit is connected to the feed point, and the second end of the first impedance matching circuit is connected to the signal source The first end is connected; the first end of the second impedance matching circuit is connected to the third end of the first impedance matching circuit, the second end of the second impedance matching circuit is grounded; the second end of the signal source is grounded. The embodiment of the present invention can reduce the voltage standing wave ratio of the antenna and improve the performance of the antenna.
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...
