Claim 0:
1. An air interface plane (AIP) of a radio frequency (RF) aperture comprising:
a circuit board having a first side and a second side opposite the first side; and
a matrix of tapered elements arranged on the first side of the circuit board and secured to the circuit board, said matrix of tapered elements cooperating to at least one of receive or transmit an over-the-air RF signal;
wherein each tapered element of the matrix comprises:
a central hub defining an apex of the tapered element which is distal from the first side of the circuit board; and
a plurality of arms extending from the central hub at the apex of the tapered element, each of the plurality of arms including a first portion that projects the arm radially away from a longitudinal axis perpendicular to the circuit board and passing through the apex and a second portion that projects the arm longitudinally toward the first side of the circuit board.
