  • Method and apparatus for controlling multi band antenna in mobile communication terminal
    Patent number: 8909166
    Abstract: An apparatus and method for controlling a multi-band antenna in a mobile communication terminal are provided. An apparatus for controlling a multi-band antenna in a mobile communication terminal includes a modem, an antenna unit, a Radio Frequency (RF) processing unit, and a switch module. The modem outputs at least one control signal corresponding to a target frequency band. The antenna unit changes a resonance frequency of the antenna according to the at least one control signal. The RF processing unit includes a plurality of transmission/reception (TX/RX) paths and processes TX/RX signals. The switch module connects the antenna to one of the TX/RX paths according to the at least one control signal.

  • Multi-band antenna for mobile phone
    Patent number: 7864124
    Abstract: A mobile phone includes a multi-band antenna which is mutually connected in a dependent manner for operation according to a signal transmitted to and received from the mobile phone; and a resonance unit for generating resonance for multiple frequency bands as ends of the multi-band antenna are spaced apart at a predetermined interval, to improve mute performance, reduce SAR, and prevent a reduction in call performance due to an influence of a user's body and hand when holding the mobile phone to make a call.
