1. A phased array antenna comprising:
a base plate configured to provide a path to ground; and
a first unit cell comprising:
a signal ear configured to capacitively couple with a first grounded pillar, wherein the first grounded pillar is connected to the base plate; and
a ground ear configured to capacitively couple with a signal ear of a second unit cell, wherein no grounded pillar is provided between the ground ear of the first unit cell and the signal ear of the second unit cell.
