antenna.s1p

hi all,if i want to insert s par. file of antenna at the input port instead 50 ohm,in order to simulate antenna plus amplifier in rx mode,how i put this file and what is its format

Save the antenna file as “antenna.s1p” and insert in your design.

WHAT IS THE FORMAT IN TEX FILE
REGARDS

The common used format to exchange s-par between intruments and simulator is TOUCHSTONE. ADS of course uses this format.
You can easily find on the web nformations on touchstone.
Hope it can help

hi,all,my certain prbolem is i want to simulate antenna integrated with
amplifier in ads,i have idea that if i have antenna s par. file
in touchstone,i may simulate i,is that right i put antenna s parameter
file in s1p extension format,that in rx mode,at the port 1 instead of
50 ohm port ,problem is if i put module of s1 in input port and upload
it with touchstone file,then simulate,the simulator says error message,
where is port 1.question (how i put antenna file at the port 1) to simulate that
antenna integrated with amplifier,port 2 at 50 ohm already
regards

You have to specify the input termination as a complex load.
Edit your termination (port nr 1), and enter for Z, the complex impedance of your antenna at one frequency (beware the format is 1+j*0). You can run the simulation just for a few in-band frequency points.
If I remember well is a possibility to load entire s-file changing “Parameter Entry Mode” to “File Based”.
