Terminal antenna system

A terminal antenna system, used in an electronic device, wherein the terminal antenna system comprises a first antenna and a second antenna;

• operating frequency bands of the first antenna and the second antenna both comprise a first frequency band;
• the first antenna comprises a first radiator, and a length of the first radiator is less than or equal to one-half of a wavelength corresponding to the first frequency band;
• and
• a first feed point and a second feed point are respectively arranged at two ends of the first radiator, the first feed point and the second feed point are respectively coupled to two signal output ends of a common mode feed structure, the two signal output ends of the common mode feed structure have a same polarity, and two signals of the common mode feed structure are equi-amplitude in-phase signals;
• the second antenna comprises a second radiator, and a length of the second radiator is less than or equal to one-half of the wavelength corresponding to the first frequency band;
• and
• a third feed point and a fourth feed point are respectively arranged at two ends of the second radiator, the third feed point and the fourth feed point are respectively coupled to two signal output ends of a differential mode feed structure, the two signal output ends of the differential mode feed structure have different polarities, and two signals of the differential mode feed structure are equi-amplitude phase-inverted signals.
