1. A phased array antenna comprising:
a plurality of unit cells, wherein each unit cell comprises:
a base plate;
a first ground clustered pillar projecting from the base plate;
a second ground clustered pillar projecting from the base plate and spaced apart from a first side of the first ground clustered pillar;
a first ground member projecting from the base plate between the first ground clustered pillar and the second ground clustered pillar; and
a first signal member projecting from the base plate between the first ground clustered pillar and the first ground member, wherein the first signal member is inserted into the base plate and is connected to a flexible conductor on a first side of the flexible conductor, wherein the flexible conductor is connected to a rigid conductor on a second side of the flexible conductor, and wherein the first signal ear, the flexible conductor, and the rigid conductor are configured to create an electrical path between the first signal ear and the rigid connector.
