Abstract
An antenna apparatus for a mobile communications terminal and its operation method in which the length of an antenna can be varied according to the changes in the usage environment. The antenna requires minimal space for installation, and can support multiplexing of frequency bands, such as tri-band or quad-band capabilities, so as to reduce the deterioration of signal transmission and reception sensitivity caused by changes in the usage environment, such as effects from the user's hand that holds the terminal, an act of opening and closing of a folder portion of the terminal, and the like.
Claims33
An antenna apparatus of a mobile communications terminal comprising:
- a first antenna;
- and
- an antenna length adjustor connected to the first antenna for varying the length of the first antenna according to a signal transmission/reception quality of the mobile communications terminal.
An antenna apparatus of a mobile communications terminal comprising:
- a first antenna;
- at least one or more second antennas;
- a switching unit for connecting the first antenna with each second antenna;
- and
- a controller for controlling an operation of the switching unit according to a signal transmission/reception quality of the mobile communications terminal, and thus varying the length of the first antenna.
An antenna operation method in a mobile communications terminal provided with a first antenna and at least one or more second antennas, comprising:
- measuring a transmission/reception quality of the first antenna;
- connecting the first antenna to each second antenna, and detecting an antenna combination for obtaining an optimal transmission/reception quality;
- and
- adjusting a length of an antenna according to the detected antenna combination.
An antenna operation method in a mobile communications terminal provided with a first antenna and a second antenna comprising:
- checking changes of an operation frequency band of the mobile communications terminal;
- and
- when the operation frequency band of the mobile communications terminal is changed, varying the first antenna into the second antenna for supporting the changed operation frequency band.
A mobile communications terminal comprising:
- a first antenna;
- at least one or more second antennas;
- at least one or more first switches provided between the first antenna and the at least one or more second antenna;
- and
- a controller for controlling the at least one or more first switches according to a signal transmission/reception quality to vary a length of the first antenna.
An antenna apparatus of a mobile communication terminal comprising:
- an antenna unit;
- and
- a controller for adjusting a physical characteristic of the antenna unit according to changes in signal transmission or signal reception, or according to a desired operation frequency band.
