Hi All,
I need to design 36" x 9" in cassegrain configuration operating in E-band (Narrow bandwidth).
I know how to design regular casssegrain but in this case I'm worry about the horn/sub-reflector blockages. Is splash plate design possible for proper illumination for that fan beam? It would be great if I can remove the spars and seems possible for narrow bandwidth operation (single frequency). Should I go with dual-offset reflector? If anybody knows good references or advises, really thanks in advance.
 


I am n o antenna expert but if you need a fan beam, you can use either prime-focus or Cassegrain or Gregory optics with an offset feed. This avoids any problems you mentioned.
 

Thanks jiripolivka,
Do you know any good reference for fan beam cassegrain design?
