[Moved]: How to calculate the track width for antenna impedance matching

HI,
I have to match the antenna impedance(50ohm).from the source 80EV0301, through the pcb track.

I had used the formula.

in above image the width has calculated as 2.78mm is this value right?.




i don't know how to calculate these values to match impedance.

please guide me the steps to do so?

i'am waiting for your reply.

thanks and regards
