Perhaps a single antenna element from the phased array in the following
JPL paper would be useful:

I don't know that Mark's antenna is the right kind of thing for GPS.
the x-pol off axis is pretty high and the construction is dependent on
having the right materials around. You could probably use a HDPE
cutting board instead of teflon and some other foam.
If you want gain in the vertical direction, why not a stacked patch with
air dielectric?
Mark's antenna in the article was eventually intended to be for a
"phased array at the focus of a reflector/reflectarray" application in
space, so fabrication of a stack was more appropriate.
