Hi,
I am trying to make a 50ohm transmission line. I have made it using the coplanar wave guide with ground plane.
I have come to the conclusion that the track has to be quite wide to get the correct impedance.
This again become a problem when I arrive at the components which are 0603(0201 im) size, and the track is way to wide for the components.
What happens if I drop down to 0.5mm the last 0.5 mm of the track, will the impedance change for the whole transmission line. If so, will the track width be limited to the width of the tuning component footprint?
Also, the via will introduce some capacitance to the track, what is the best way to place the via, close to the antenna element, or close to the input on the Microcontroller?
Thanks in advance
