feed line equation

Hello,
Is there an equation to calculate the feed line of a rectangular microstrip path either for a 50 or 100 ohms.

thank you very much

here are two examples

Re: Microstrip feed line

thanks
but I'm looking at something that has formulas and i want to calculate the width of the feed line not the square patch.


Thanks
