Abstract :
An adaptive antenna, which consists of a feed element and some circular arrays of parasitic elements on the counterpoise and forms adaptive pattern by connecting the each parasitic element to switched load us proposed. In this paper, the antenna aperture, that is, number of parasitic elements, number of circular arrays and the radius, and the switched load are examined by the Monte-Carlo simulation.
