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 tracking system for use with an arrow including a base unit defining an open central section; a holding magnet positioned within the open central section; and a sending unit that includes an electronic circuit; a main body section affixed to an electronic circuit; projections extending from the main body section into the open central section and at least partially surrounding the holding magnet; and a projection extending from the main body section and ending in a point; where the electronic circuit includes a battery and is constructed to emit a tracking signal when activated and the electronic circuit includes a magnet switch element such that the electronic circuit is maintained in a deactivated state as a result of the magnetic field established by the holding magnet.
