International Classification:

H01Q 928

US Classification:

343795, 343865

Abstract:

An apparatus for coupling a signal supply with an antenna including first and second elements. The signal supply delivers a signal to the antenna at a connection locus. The first element has a first edge and the second element has a second edge; the connection locus includes part of the first and second edges. The apparatus includes a first and second feed structure. The first feed structure extends a feed distance from the signal supply to the second edge and divides the first element into two lands in spaced relation with the first feed structure to establish a separation distance intermediate the first feed structure and the two lands. The second feed structure couples the signal supply with the first proximal edge. The separation distance establishes a signal transmission structure between the two lands and the first feed structure.

Abstract:

A semi-coaxial horn antenna transmits and receives electromagnetic waves, including impulse radio waves. The antenna includes an inner conductor that is surrounded by a cone-shaped dielectric, and an outer conductor that is conformally attached to the cone shaped dielectric. In embodiments, the inner conductor is a hollow metallic cylinder that is able to slide over a separate metal shaft, which may be part of a portable hand-tool device. The dielectric constant of the cone shaped dielectric may be selected to match a target medium. The outer conductor has a cross-section that is substantially an arc shape, and defines a sector angle that determines an impedance along the length of the antenna.

US Classification:

343700MS, 343741, 343866

Abstract:

An apparatus for conveying electromagnetic energy intermediate a host device and a medium substantially adjacent to the apparatus includes: (a) a transceiver for transmitting the energy to and receiving the energy from the medium; (b) a transmission structure for conveying signals to or from the host device; and (c) a feed structure coupling the transceiver with the transmission structure. The transceiver includes a planar metal layer arrayed upon a dielectric substrate. The metal layer is bounded by a first edge and a second edge. The first and second edges cooperate to form a bight having a first and a second arm establishing a metal-free area intermediate the first and second arms. The first arm presents a first terminal locus and the second arm presents a second terminal locus. The feed structure is coupled with the first and second terminal loci to effect the coupling.

Abstract:

An intrusion detection system and method are provided that can utilize impulse radio technology to detect when an intruder has entered a protection zone. In addition, the intrusion detection system and method can utilize impulse radio technology to determine a location of the intruder within the protection zone and also track the movement of the intruder within the protection zone. Moreover, the intrusion detection system and method can utilize impulse radio technology to create a specially shaped protection zone before trying to detect when and where the intruder has penetrated and moved within the protection zone.

International Classification:

G01S 1304

US Classification:

343893, 342 27

Abstract:

An antenna array comprising a ground plane and a plurality of elements mounted thereon, said elements being capable of emitting and receiving ultra wideband emissions. Elements are arrayed on the ground plane in two parallel rows, a transmitting row, and a receiving row, such that a given element in the receiving row is aligned in at least one direction with a corresponding element in the transmitting row. Additionally, the elements are configured on the ground plane to elicit a symmetrical product response in the azimuthal plane, and to produce horizontally polarized signals. An alternative embodiment places the elements with unique inter-element spacing within the rows. An embodiment comprises a fence structure between rows. A method for use comprises the step of transmitting a signal via an element in the transmitting row and receiving said signal through an element in the receiving row, not aligned with the transmitting element.

US Classification:

343742, 343741, 343866

Abstract:

An electromagnetic antenna apparatus exhibits a generally continuous signal response between a first frequency and a second frequency, and further exhibits a deviation from the signal response in a frequency region centered substantially at a selected frequency between the first frequency and the second frequency. The apparatus includes: (a) an antenna transceiving element; (b) a feed structure coupled with the antenna receiving element for communicating transceiving signals with the antenna transceiving element; and (c) a discontinuity structure in the antenna transceiving element coupled with the feed structure. The discontinuity structure is configured for effecting return of selected transceiving signals to the feed structure as return signals. The return signals effect the deviation.
