I don't know where you are presently at with this project, but have you thought of a helical ( circular polarized ) antenna since you have 2' of space under the flooring??

If you are still active with this project, have you investigated the idea of using a UHF FET front end and building an E-probe in that small area?
Always a good way to get a smaller but efficient antenna.

cam,
DBi alludes to a radiator which illuminates equally in all directions. Equal apeture...
The 'i' stands for Isotropic, the closest demonstration being a lightbulb but even the base keeps it from being a perfect ISOTROPIC radiator...
A simple dipole has some gain over a isotropic because it...
I think you can accomplish your goal by keeping the loading inductor at a small diameter and squeeze/lengthen it ( coil ), if not adding or subtracting turns...
The effective height 'G' will remain about the same...
Also think about top loading @ 6ghz., no problem...

BLL,
Think about 3 rotary ( manual ) coax switches cobbed together and modified with one shaft extending down through the wafers of your new 3 layer package..
Yes??
