Abstract: An air interface plane (AIP) of a radio frequency (RF) aperture includes: 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, the matrix of tapered elements cooperating to at least one of receive or transmit an over-the-air RF signal. Suitably, each tapered element of the matrix has: a central hub extending along a longitudinal axis from a hub base which is proximate to the first side of the circuit board to an apex of the tapered element which is distal from the first side of the first 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 the longitudinal axis and a second portion that projects the arm longitudinally toward the first side of the circuit board.

Abstract: A system and method for projecting a holographic image of an object, the system preferably comprising a mobile or smart phone having a power supply source; a central processing unit; software provided by the smart phone for transforming a two dimensional image to project an untethered or seemingly suspended holographic image, the smart phone preferably providing the light source and a holographic, table top projection device having a display window configured to permit the holographic image to be projected therethrough and into space adjacent to the table top device, wherein the optical elements for enabling the holographic projection, namely, a spherical mirror, a circular polarizer, and a beam splitter are housed in the table top device and the same is provided with a slot or pocket configured to hold and maintain the smart phone in mechanical and electronic connection to the table top device.
