microwave filter design - simulation and fabrication

hello,
I need to simulte and fabricate low pass and high pass filter using microstrip line using stubs and stepped impedance for my project
the range of frequency is L band and substrate is fr4.
I am having problem in calculating the parameters because i am not having simulation results to cross varify...
can any one provide me the simulation result....

Nobody knows your filter specifications.How they will help you?

U need to first design ur filter using the desired specifications in an appropriate software like IE3D, ADS or HFSS. Upon designing, you will obtain the simulation results which you can use for fabrication.

if you dont have simulation results than simulate in ADS and verify your self
