Abstract: A communication system comprises a signal generator, polarizer, signal combiner, transmitter, positioning device, and controller. The signal generator converts first and second received data streams into respective first and second orthogonal linearly polarized signals. The polarizer is at a first rotation angle and converts first and second orthogonal linearly polarized signals into, respectively, a first right-hand-circularly polarized (RHCP) signal and first left-hand circularly polarized (LHCP) signal, which are combined in signal combiner into a signal sent by transmitter to a receiver. The positioning device adjusts the first rotation angle to substantially increase isolation between third and fourth orthogonal linearly polarized signals at the receiver. The controller performs the real-time analysis of transmission loss and directs the positioning device to adjust the first rotation angle.

Abstract: An antenna system is provided having a ground plane and a first antenna element disposed over the ground plane. The first antenna element includes first and second fins, each of the first and second fins having an input port and a shape selected such that the fin is responsive to electromagnetic signals provided thereto. The antenna system further includes a second antenna element disposed over the ground plane. The second antenna element includes third and fourth fins, each of the third and fourth fins having an input port and a shape selected such that the fin is responsive to electromagnetic signals provided thereto. The first and second antenna elements are orthogonally arranged with respect to each other such that a slot portion of each of the first and second antenna elements intersect. The antenna system further includes a first substrate disposed about the first and second antenna elements.

Abstract: A system for triggering improvised explosive devices (IEDs) with an alternating magnetic field. In one embodiment, the magnetic field is produced by a magnetic field projector in the shape of one-half of a torus, the half-torus being composed of several conductive segments referred to as toroidal wedges. A poloidal current flows in each toroidal wedge, producing a magnetic field that is projected by the half-torus. The magnetic field may induce a current, producing heating, in a conductive loop in an IED and triggering the IED.

Abstract: A multiple input loop antenna comprising one or more half-loop antennas disposed above a ground plane wherein the plane of each half loop is perpendicular to the ground plane such that the multiple input loop antenna is a three-dimensional structure and electromagnetic waves are radiated from points within the volume occupied by the antenna rather than from a two-dimensional surface. For this reason, the multiple input loop antenna can radiate levels of peak power without inducing excessive air breakdown which are relatively high compared with peak power levels of conventional antennas having comparable transverse dimensions. Also described is an array antenna comprised of an array of multiple input loop antennas.
