Abstract
IEEE AP-S, Vol. 37, No. 6, June 1989, pp. 683-689The article of record as published may be located at http://dx.doi.org/10.1109/8.29354The E-field integral equation is applied to rotationally symmetric reflector antennas with struts. Current is allowed to flow on all the reflector surfaces and continuity is enforced at the conductor junctions. Radiation patterns are presented for a small paraboloid antenna, and the effects of the struts are clearly identified. These include the strut cone radiation, pattern asymmetries introduced by the struts, and gain loss and sidelobe level changesKeywords
