An antenna system for controlling multi beam independently and a base transceiver station using the same are disclosed. The multi beam controllable antenna system includes: at least one first dividing unit for dividing an input signal into a plurality of first divided signals; at least one first phase shifting unit for shifting the first divided signals and generating first phase-shifted signals; at least one first combining unit for combining the phase-shifted signals and generating a combined signal; at least one second dividing unit for dividing the combined signal into second divided signals; at least one second phase shifting unit for shifting the second divided signals and generating second phase-shifted signals; and a controlling unit for generating a control signal which controls horizontal and vertical half-power beam widths and tilting angles of the input signal independently by controlling the first and the second dividing unit and the first and the second phase shifting unit.
