Inhalt:
We propose a novel antenna design method consisting of the gradient method and method of moment is proposed. An antenna structure is represented by the combination of small segments. By regarding the 0/1 state segment variable as a real parameter, a matrix equation for the gradient method is derived. Fast computation causing of automatic decisions of simultaneous changing segments achieves practical design for various antennas, including large-scale antennas.
