Abstract

PURPOSE:To obtain an optimum antenna pattern, by securing a close distance of the center axis among plural primary radiators with use of the horns having different shapes with symmetrical center axes. CONSTITUTION:A step horn 12a is used for a primary radiator that supplies the maximum electric power. At the same time, a circular horn 12b and a deformed circular horn 12c having symmetrical center axes are used for a primary radiator having a small amount of supplied electric power. The horn 12c is formed by recessing a part of the circular horn in order to decrease the distance between its center and the center of the horn 12a. Thus it is possible to distribute the horns 12c and 12a at the optimum positions. As a result, a desired beam can be easily formed. A rectangular horn or a corrugated rectangular horn can substitute for the horn 12b.
