Antenna switching method and terminal antenna

An electronic device, comprising a terminal antenna, the terminal antenna comprising:

• a first radiator, wherein a structure of the first radiator is a closed ring structure;
• wherein the first radiator comprises at least three electrical connection points, the at least three electrical connection points comprise a feed point and at least two ground points;
• wherein an operating state of the terminal antenna comprises a first state and a second state, the terminal antenna in the first state has a first polarization characteristic, and the terminal antenna in the second state has a second polarization characteristic;
• wherein the at least two ground points comprise a first ground point, the first ground point is connected to a first end of a tuning component of the terminal antenna, a second end of the tuning component is connected to a reference ground, the tuning component comprises a first path and a second path, and the tuning component is configured to control the terminal antenna to operate in the first state or the second state according to the following:
• the tuning component is configured to control the first path to be in an on state when an attitude of the electronic device is a first attitude, to cause a polarization characteristic of the terminal antenna to be the first polarization characteristic;
• and
• the tuning component is configured to control the second path to be in an on state when an attitude of the electronic device is a second attitude, to cause the polarization characteristic of the terminal antenna to be the second polarization characteristic;
• and
• wherein the first attitude is different from the second attitude, and the first polarization characteristic is different from the second polarization characteristic.
