If you are designing complex networks of power dividers, combiners and couplers using standard structures like common transmission lines, coupled lines, etc. what you need is a circuital software. A good starting point is QUCS, which is simple and free.
Qucs project: Quite Universal Circuit Simulator

If you are designing not networks, but specific elements where circuital models don't provide a good enough accuracy, you need a electromagnetic software. In this case, there are not many free simulators. May you can try Sonnet.
Sonnet Lite

Hello govardhanamma,

Are these microwave circuits are based on planar transmissionline implementation such as microstrip/stripline/cpw?
If so use Sonnet Lite 13.51 which is free electromagnetic simulator based on Method of Moments....
Free Download - Sonnet Lite

Also it has many built in examples on Filters, combiners, dividers, etc...see here
Sonnet Lite Applications - Sonnet Software

Thanks manju,
my microwave circuits are designed by using microstip lines,is it possible yo design couplers using sonnet software?

Hello govardhanamma,

Yes it is possible to design microstrip couplers using Sonnet em simulator...

hi govardhanamma.
we dont have good free software for EM simulation
i usually suggest HFSS because it is user friend software

HFSS for planar circuits makes not much sense. Why not use a planar solver, which is more accurate for planar model and easier to use by any means (stackup, port defintions).
