Antenna system and electronic device

An electronic device, comprising an antenna system comprising a first antenna, a second antenna, and a tuning stub, wherein the first antenna and the second antenna have a same first operating frequency band;

• wherein the tuning stub is electrically connected to the first antenna, and the tuning stub is configured to adjust an equivalent current path of the first antenna;
• wherein a connection line between a projection point of a maximum equivalent current point of the first antenna and a projection point of a maximum equivalent current point of the second antenna on a first plane and a projection of the equivalent current path of the first antenna on the first plane form a first included angle before the first antenna loads the tuning stub, and form a second included angle after the first antenna loads the tuning stub;
• wherein the connection line between the projection point of the maximum equivalent current point of the first antenna and the projection point of the maximum equivalent current point of the second antenna on the first plane and a projection of an equivalent current path of the second antenna on the first plane form a third included angle before the first antenna loads the tuning stub, and form a fourth included angle after the first antenna loads the tuning stub;
• and wherein a projection of the equivalent current path of the first antenna and a projection of the equivalent current path of the second antenna on a second plane form a fifth included angle before the first antenna loads the tuning stub, and form a sixth included angle after the first antenna loads the tuning stub, wherein the first included angle to the sixth included angle are all less than or equal to 90 degrees;
• and wherein the second included angle is greater than the first included angle, or the fourth included angle is greater than the third included angle, or the sixth included angle is greater than the fifth included angle.
