Abstract

PURPOSE:To achieve a radiation characteristic symmetrical rotatably with low side lobe, over a broad band, by locating four pyramid horns through taking a corrugated horn as a center. CONSTITUTION:A corrugated horn at the center consists of a circular cone type horn 9 at the external circumference and perforated disc type fins 10 periodically located along the tube axis of the horn 9. Four pyramid horns 11a-11d are provided around the corrugated horn 8. Thus, an antenna primary radiator in common use for multifrequency with excellent electrical performance of the horn 8, i.e., symmetrical radiation characteristics rotatably with low side lobe over a wide band is obtained, and sum and difference patterns even at separate frequencies can be obtained with the four pyramid horns 11a-11d at the circumference.
