Hello Vargas , our initial try was from 1 GHZ we tried changing all parameters but we are not able to get a flat curve below 10dB from 1 GHz. There are some bumps between 1 and 4 GHz. That's mainly because Vivaldi antenna works well for higher frequencies. Well if any luck you can try changing all the widths, lengths and try it on your luck. LMK if you successfully designed. Thanks and cheers.
@@shriharipapa What variables do I have to modify to vary the width and length of the conductor patch? Because Sub X and Sub Y modify only the substrate. I have tried modifying the variables "w" and "l" but without success. Please if you can guide me. Thanks.
@@cesarmezzich you have to try everything man , from the transmission line to patch sizes. I am sorry I am not much of a help . But there is no exact design equations for anti-podal Vivaldi antennas.
the file in gut hub gis not availbel
Dear Shrihari Mohan, in the return loss graph, what parameter can I modify so that the reflection in 10 dB is from 2GHz? Thanks for your answer.

Se pueden exportar la antena o sus propiedades a matlab?
Is any file available or
The x and y equation for the cure is it available ?
I will update my GitHub repository and reply in this comment again. Hope you can wait for some days.
How u draw that curve bro
You can use the files provided in the github
Hola necesito de tu ayuda para una simulación en hfss de una antena Vivaldi antipodal
Sí, ¿puedes decirme en qué parte necesitas mi ayuda?
