PURPOSE: A side-lobe characteristic controlling antenna is provided to supply smooth wireless communication services by reducing interference signals and signals to be interfered. CONSTITUTION: A power coupler(214) receives a signal to be transmitted and generates a main channel signal and a sub-channel signal. The main channel signal and the sub-channel signal are outputted. A main channel power distributor(240) receives the main channel signal and distributes the power of the main channel signal. A main antenna(270) includes one dimensionally or two dimensionally arrayed antenna structure composed of a plurality of antenna elements. A vector signal controller(230) controls the amplitude and the phase of the sub-channel signal. A sub-channel power distributer(250) distributes the power of the sub-channel signal. |
