摘要：

This paper deals with a class of feed antennas and feed antenna arrays, used in the focal plane of paraboloid reflectors, which exhibit higher than normal levels of crosspolarized radiation in the diagonal planes. A model is presented which enables prediction of element gain, and aperture efficiency of the feed / reflector system, in good agreement with experimental results. Tapered slot antenna (TSA) elements are used as an example of an element of this type. It is shown that TSA arrays used in multibeam systems with small beam spacings are competitive in terms of aperture efficiency with other, more standard types of arrays, which incorporate waveguide type elements. © 1990 IEEE
