PROBLEM TO BE SOLVED: To provide an antenna system and an antenna system operating method capable of forming and controlling FA beam widths in a sector to various forms by making the vertical/horizontal half-power beam widths and tilting angles of each FA in the sector respectively independently variable. SOLUTION: This multi beam controllable antenna system includes at least one first dividing means for dividing an input signal and generating many first divided signals, at least one or more first phase controlling means for controlling the phases of the first divided signals and outputting first phase control signals, a first combining means for combining the first phase control signals and generating a first combined signal, at least one or more second dividing means for dividing the first combined signal and generating many second divided signals, at least one or more second phase controlling means for controlling the phases of the second divided signals and outputting a second phase control signal, and a controlling means for generating a control signal which controls horizontal/vertical half-power beam widths and tilting angles of the input signal independently by controlling the first and the second dividing means and the first and the second phase controlling means.
