Abstract
An antenna using a liquid metal is provided. The antenna includes a plurality of antenna structures, each having an inner cavity of a form corresponding to a radiator pattern; and at least one actuator connected to at least two of the plurality of antenna structures to control movement of the liquid metal to supply the liquid metal to at least one of the antenna structures. Thereby, deterioration of an antenna performance due to an influence of a human body can be prevented, and deterioration of an antenna performance can be prevented due to a form change of an electronic device including the antenna. In this manner, optimal antenna radiation performance can be dynamically realized.
Claims9
An antenna using a liquid metal, comprising:
- an antenna structure comprising an elastic tube containing the liquid metal at an inner space;
- and at least one actuator positioned in mechanical relation to the antenna structure to change at least one of a position or dimension of a radiator formed by the liquid metal by pressing a partial area of the antenna structure according to a control signal, the pressing deforming the partial area and causing at least some of the liquid metal to move out of the partial area to another location of the antenna structure and thereby cause the change in at least one of a position or dimension of the radiator, wherein if the partial area is not pressed, at least some of the liquid metal is disposed therein and forms at least a part of the radiator, and wherein the at least one actuator comprises a plurality of actuators disposed in a sequence at one or more ends of the antenna structure.
An antenna using a liquid metal, comprising:
- an antenna structure comprising an elastic tube containing the liquid metal at an inner space, the antenna structure including a partial area that, prior to being pressed, contains at least some of the liquid metal and forms at least part of a radiator;
- and
- at least one actuator positioned in mechanical relation to the partial area of the antenna structure and operable, according to a control signal, to deform the partial area by pressing sufficiently to cause liquid metal contained in the partial area to move to another location of the antenna structure, so that the partial area no longer forms at least part of the radiator, thereby changing at least one of a position or a dimension of the radiator.
