Terminal antenna and method for controlling beam direction of antenna

An electronic device, comprising:

• a first chip and a terminal antenna;
• wherein the terminal antenna comprises:
• a first radiator, a second radiator, and a switch module, wherein the first radiator and the second radiator are patches;
• the first radiator is connected to a first end of the switch module, and the second radiator is connected to a second end of the switch module;
• the first radiator is provided with a feed point;
• a working status of the switch module comprises an on state and an off state;
• the first radiator and the second radiator have the same long side length;
• and
• neither of the first radiator and the second radiator is provided with a ground point;
• the first chip is connected to the switch module and the feed point separately;
• the terminal antenna is configured to receive a to-be-detected signal sent by a to-be-detected object;
• the first chip is configured to obtain the to-be-detected signal through the feed point;
• and
• the first chip is further configured to control the working status of the switch module according to strength of the to-be-detected signal;
• wherein when the working status of the switch module is the on state, and the strength of the to-be-detected signal is less than a first threshold, the first chip switches the working status of the switch module to the off state;
• or
• when the working status of the switch module is the off state, and the strength of the to-be-detected signal is less than the first threshold, the first chip switches the working status of the switch module to the on state.

A method for controlling a beam direction of an antenna, wherein the method is for positioning a to-be-detected object and is applied to an electronic device;

• wherein the electronic device comprising a first chip and a terminal antenna;
• wherein the terminal antenna comprises:
• a first radiator, a second radiator, and a switch module, wherein the first radiator and the second radiator are patches;
• the first radiator is connected to a first end of the switch module, and the second radiator is connected to a second end of the switch module;
• the first radiator is provided with a feed point;
• a working status of the switch module comprises an on state and an off state;
• the first radiator and the second radiator have the same long side length;
• and
• neither of the first radiator and the second radiator is provided with a ground point;
• the first chip is connected to the switch module and the feed point separately;
• the terminal antenna is configured to receive a to-be-detected signal sent by a to-be-detected object;
• the first chip is configured to obtain the to-be-detected signal through the feed point;
• and
• the first chip is further configured to control the working status of the switch module according to strength of the to-be-detected signal;
• the method comprises:
• receiving, by the terminal antenna, a to-be-detected signal sent by a to-be-detected object;
• and
• controlling, by the first chip, the working status of the switch module according to strength of the to-be-detected signal;
• wherein the controlling, by the first chip, the working status of the switch module according to the strength of the to-be-detected signal comprises:
• controlling, by the first chip, the working status of the switch module to be the on state when an inclination angle of the electronic device is greater than a first preset angle;
• and
• controlling, by the first chip, the working status of the switch module to be the off state when the inclination angle is less than or equal to the first preset angle.
