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

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

how to find air gap width for a batch antenna feed any way?or formula or thump rule?

In what section of the balanis book is the formula to calculate the width of the feed line.

thank uuu

Hello Sundar,
I got the problem which you told in balanis. But how do u calculate g12? bcoz that is required or calculating the feed point.

is it this equation valid for half wave dipole microstrip antenna?
