Claim 10:
11. A communications terminal, comprising an antenna structure, wherein 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 is coupled to the second antenna radiator through a slot, an end of the first antenna radiator away from the slot is grounded, a feed point is disposed on the first antenna radiator, an end of the second antenna radiator away from the slot is grounded, a length of the first antenna radiator is greater than a length of the second antenna radiator, and an absolute value of a difference between the length of the second antenna radiator and a ¼ wavelength of a third frequency band is less than a first specific value;
a first terminal of the first impedance matching circuit is connected to the feed point, and a second terminal of the first impedance matching circuit is connected to a first terminal of the signal source;
a first terminal of the second impedance matching circuit is connected to a third terminal of the first impedance matching circuit, and a second terminal of the second impedance matching circuit is grounded; and
a second terminal of the signal source is grounded;
wherein:
the first impedance matching circuit comprises a first inductor, a first capacitor, and a second capacitor;
a first terminal of the first inductor is connected to the feed point, and a second terminal of the first inductor is connected to a first terminal of the first capacitor;
a first terminal of the second capacitor is connected to the feed point, and a second terminal of the second capacitor is connected to the first terminal of the first capacitor; and
a second terminal of the first capacitor is connected to the first terminal of the signal source.
