Can any one provide calculations for feed point on ceramic substrate used in GPS antennas?

The position of the feedpoint is important as it should present a 50 Ohm impedance.
 

May it helps

The majority of the PatchAntennas use a probe feed coming from the bottom side. If this is the point you're trying to find to get a good match, this article should help.
