Antenna, antenna control method and device, and terminal

An antenna applied to a terminal, the antenna comprising:

• an antenna radiator container, an amorphous antenna radiator, and an antenna radiator control unit, wherein
• the antenna radiator container is provided with a sealed accommodating cavity;
• the amorphous antenna radiator is provided in the accommodating cavity of the antenna radiator container;
• and
• the antenna radiator control unit is connected with the antenna radiator container and is configured to control a configuration of the amorphous antenna radiator in the accommodating cavity, wherein the configuration comprises a relative position of the amorphous antenna radiator in the accommodating cavity, or comprises a shape of the amorphous antenna radiator, or comprises a relative position of the amorphous antenna radiator in the accommodating cavity and a shape of the amorphous antenna radiator,
• wherein the accommodating cavity is provided therein with a plurality of separators dividing the accommodating cavity into tubular sub-cavities.
