    摘要： The invention relates to a tunable antenna installed inside a mobile communication terminal to process multiple bands according to selection of reception frequency of a signal, and a control unit therefor. The tunable antenna includes an antenna for processing at least two different RF signals and an RF processor for receiving the RF signal from the antenna through a data signal line to convert the signal to a baseband signal. The tunable antenna further includes an antenna controller for providing a direct-current control signal for converting a band processed by the antenna through the data signal line, and an antenna tuner for receiving the direct-current control signal to convert the band processed by the antenna.
