folks;
hi all
i have got an important thing to ask for both users of hfss and cst
i would like to simulate a real switch that connect 2 microstrip lines ,i already have the s parameters (s2p file for the switch),but i do not know how to do it,
input port ----->>microstrip----switch data---another microstrip
my problem here is how to define the ports at both edge of the virtual switch block diagram (e.g at the end of the 1st microstrip and at the start of the second microstrip)
You can do it in CST Design Studio. There you can choose a Touchstone file in the Block selection tree "Data import" and add it as a block. You can add other electric elements and also create a model around it.
cheers folks
ok that is fine ,,i had my switch block linked with the s parameter file ,but how to
link the ports of the box with the ports in the cst patch antenna microwave simulation.
in another words what i am really simulating is a patch antenna with a microstrip feed.i want to insert this switch into the feed ,please find attached an illustrative image .
1) The usual method is to simulate the EM part in the EM simulator, with ports for the components.
Then, all components and the EM blocks are combined in a circuit simulator like ADS, MWO etc. to give the "complete" result.
2) There are some EM simulators where you can insert subcircuit blocks into the EM model. This will give the same results as 1)
in MicroWave Studio you can add one port for your switch and one for the output. Then choose in Design Studio the option differential ports. So you can connect your switch at this differential port.
