Abstract
The electrical properties of a conical horn-reflector antenna of 2-deg rees - 3-degrees beam width have been investigated over the frequency range of 12-18 GHz. We show that the employment of a corrugated horn r educes the characteristic spillover side lobe of the conical horn-refl ector antenna by 15 dB and yields excellent main beam circularity over the full Ku band. This results from the taper of the field amplitude toward the edges of the horn aperture in both the E-plane and the H-pl ane illumination. The performance of the antenna makes it suitable for use in closely packed interferometers for radio astronomy.
