Hi,
i'm working with microstrip antenna and i use Txline sortware to determine the line dimension, but in the software i have to put the constant dielectric. My question is i have to put the constant dielectric or the effective?

I hope anyone can help!!!

Best regards,

I believe most software has you input the relative permittivity and calculates the effective for you. I know that ADS and HFSS do, but I've never used Txline...
