Summary:PURPOSE: A butler matrix and a multi-port amplifier including the same are provided to minimize phase change by removing a loss and a distortion of a signal through the separation of transmission lines. CONSTITUTION: A hybrid(HYB1 to HYB12) includes an input terminal and an output terminal. Waveguides(15,16,25,26,37,38,47,48,59,79,510,611,612,710,811,812) transmit a signal between the hybrids. A butler matrix has four hybrids to make 4 X 4 butler matrices.
