An E-field integral equation solution for the radiation from reflector antennas with struts

The 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 defined. These include the strut cone radiation, pattern asymmetries introduced by the struts, and gain loss and sidelobe level changes.<
