Think about this analogy.  Place a round balloon on a flat surface, put
another flat surface on top of the balloon and apply pressure.  The
balloon
will change  shape spreading out horizontally but does not get larger in
volume.  This is similar to what happens when antennas are stacked
horizontally.
