Scanning dual reflector antenna

William John British Aerospace P.L.C. Hall
TL;DR: In this article, a convex auxiliary antenna is used to produce a virtual image of the feed at the focal point of the main antenna, which can be used to reduce the separation of the antenna from the main one during a scan.

A uniform geometrical theory of diffraction for an edge in a perfectly conducting surface

R.G. Kouyoumjian, +1 more
TL;DR: In this article, a compact dyadic diffraction coefficient for electromagnetic waves obliquely incident on a curved edse formed by perfectly conducting curved plane surfaces is obtained, which is based on Keller's method of the canonical problem, which in this case is the perfectly conducting wedge illuminated by cylindrical, conical, and spherical waves.

Microwave antennas derived from the cassegrain telescope

P. Hannan
- 01 Mar 1961 - 
TL;DR: In this paper, the fundamental performance of a Cassegrain double-reflector system was analyzed by means of the equivalent-parabola single reflector concept, and a set of polarization-operative surfaces was developed for these twisting antennas.
