It is possible to use a parallel plate capacitor as an antenna to pick up the electric component of an electromagnetic signal ? Thanks .
 
Engineering news on Phys.org
i guess not because the armatures would shield out the electric field...

Not a closely-spaced capacitor, but there is a variation on dipole antennas that uses capacitive "top hats" or end plates. It is similar in concept to center-loaded dipoles or monopoles, where you use an inductance in the middle of the element to make it look electrically longer:
