Antenna simulation..........

I want to work on a parabolic antenna. Could you please tell me a good software for simulation purpose (excluding HFSS and CST) ? Thank you.

The specialized software for parabolic antennas is TICRA, from Denmark. I haven't used it but I know that this is their specialty.

If you would like a general purpose solver which is also good for parabolic antennas, then you could try MoM solvers.

WIPL-D can solve very large parabolic antennas using rigorous higher order MoM, so this can be a good option. You should try it out.

When using FEKO, you would probably have to go to a hybrid MoM/PO solution for larger parabolic antennas, and would probably able to solve the smallest ones by pure MoM.

try grasp9 from TICRA.

Student version available.

Thank you very much Drasko. You have been very helpful.

And also thanks to kohi_boy.
