As a rule of thumb, Mark, I would suggest "several wavelengths", say 1 
metre, although quite how concepts such as capture area apply to active 
antennas I am not sure.  If the gain of the patch is not high, implying a 
small capture area, perhaps 1-2 wavelengths might be fine.  This is 
assuming there is no electrical interference between the devices (and I 
don't see why there should be).
