I need a ground plane under the module,
and so am looking for a "vector" board with strips, but without plated
through holes and ideally a solid ground plane on the reverse side.

o Quite useful if there aren't too many pads involved: start with
double-sided copper-clad. Score one side as needed with a utility or
XActo knife, and pull up the unwanted copper. I do this occasionally
for SOIC parts, 0.05" lead spacing; it's very quick for small hacks.

Also, consider using the E.F. Stahler or equiv. mini-mill bits to
drill out pads on the component side; this is a canonical method
of building high-frequency pcb prototypes. You then have large
copper fill on the component side as well as the reverse side plane.
