Reflector antenna with very low sidelobe level - RF Cafe Forums

The original RF Cafe Forums were shut down in late 2012 due to maintenance issues - primarily having to spend time purging garbage posts from the board. At some point I might start the RF Cafe Forums again if the phpBB software gets better at filtering spam.

Below are the old forum threads, including responses to the original posts.

Posted: Sun Jan 23, 2005 10:39 pm 
Antenna Diameter : 1.25 meter
Freq : 7.25~8.4 GHz
Efficiency : 60%
First Sidelobe level : -14 dBc
Sidelobe level : 32-25log(theta)
Type : (Cassegrain. Gregorian, ADE whatever)

It's very hard to satisfy that spec (SLL).
This Antenna is 30 lambda big, and our customer request 32-25log(rheta).
(It should be 52-10log(L/D)-25log(theta) by ITU Recommend Regulations though)
If anyone knows any product, please let me know...
