Got one CPATCH12… Looks OK, but pricey – i want to do large phased array, so i measured dimensions and will try to make it on other materials (original material – black FR4, probably requires some modifications if dielectric material changes).
Anyway, pics (with active part visible – i put microcontrast at max), dimensions (active part) and 3D drawing below.
Measured VSWR on this antenna (thanks, Laidukas):
Bad part – included connector is shorted inside – shield is soldered with center element:
EDIT: did homemade clone (copper clad PCB, knife, pliers) and tested in forest, does not look bad:
