Abstract
An electronic scanning antenna which effects radiation beam scanning based on a phase electronic scanning. The antenna has a plurality of radiation aperture units and power is fed concurrently to the plurality of radiation aperture units within a range of a small elevation angle. Thus, the degradation of a beam is reduced and a narrow beam can be formed with a high efficiency. Further, the antenna is configured wherein an electric field distribution on a radiation aperture plane formed by at least one radiation aperture is set so as to correspond to an electric distribution based on a predetermined design, thereby always normally maintaining aperture efficiency and radiation characteristic of a radiation beam over a range of a predetermined scanning angle.
