Keywords: | Antenna feeds;Antenna radiation patterns;Aperture antennas;Diffraction;Sensitivity | Issue Date: | 2017 | Publisher: | IEEE | Conference: | 2017 IEEE Antennas and Propagation Society International Symposium, Proceedings | Abstract: | This paper investigates the aperture efficiency performance limits of the shaped offset Gregorian reflector antennas with single pixel feeds, as used for the Square Kilometre Array (SKA) radio telescope. A parameter study of a theoretical feed defined by a number of spherical modes, limited by the physical dimension, is performed. The results are compared to practical feeds. | URI: | http://hdl.handle.net/11189/6438 | ISSN: | 1947-1491 | DOI: | http://dx.doi.org/10.1109/APUSNCURSINRSM.2017.8072537 |
