Methods for forming a null by only phase control based on search algorithm require complex calculations. This paper presents a method based on beam superposition without search algorithm. Due to this method, optimum phase are obtained directly by simple calculations. To confirm the usefulness of this method, experiments carried out by using circular-arc antennas have been done. Results of experiments show that a deep null can be formed at desired directions.
