Import CSV in FEKO to generate a frequency signal

Hello everyone, I am currently trying to simulate an ADS-B transmitter antenna in FEKO. The antenna design is done, and I want to change the source voltage to a desired signal (PPM signal), which has been logged in a CSV file.

Is there a way to import the CSV file into FEKO and generate the signal?

Thanks for the help.

Regards

Darnel

Hi Darnel,

You should be able to use the Time Signal feature in POSTFEKO to do this. When you create a Time Signal, you can Specify Points Manually and here you can import points in .csv format:

You will have to cull the data down to just one pulse, as in Feko we will assume an infinite pulse that it will be expanded to. Additionally, you will need to define your frequencies of simulation based off of this time signal: https://help.altair.com/feko/topics/feko/user_guide/postfeko/time_signal_vs_frequency_feko_c-postfeko.htm

Does this help, or do you have any other questions or issues?

Respectfully,

You may actually use the whole pulse, now that I think about it. As long as it is symmetric for the time band.

Glad I could help!
