1. A unit cell of a phased array antenna comprising:
a base plate;
a first ground member and a first signal member formed by at least one conductive layer disposed on at least one dielectric layer that projects from the base plate; and
a ground pillar,
wherein the first signal member is disposed between the ground pillar and the first ground member, the first signal member is electrically isolated from the ground pillar and the first ground member, and the first signal member is shaped to encapsulate at least a portion of the ground pillar such that the portion of the ground pillar is positioned between at least two portions of the first signal member and configured to capacitively couple to the ground pillar.
