  • Patent number: 6882318
    Abstract: A mono-band planar inverted F antenna (PIFA) structure comprises a planar radiating element having a first area, and a ground plane having a second area that is substantially parallel to the radiating element first area. An electrically conductive first line is coupled to the radiating element at a first contact located at an edge on a side of the radiating element. The first line is also coupled to the ground plane. An electrically conductive second line is coupled to the radiating element at second and third contacts located along the same side as the first line, but at different locations on the edge than the first contact. Useable bandwidth of the PIFA is increased by using multiple contact locations to couple the conductive second line to the radiating element. The first and second lines are adapted to couple to a desired impedance, e.g., 50 ohms, at frequencies of operation of the PIFA.

  • Patent number: 6819298
    Abstract: A high-power microwave antenna in which, in order to radiate a pulse (8), the antennas (4) of the high power microwave are actuated by a pulse-generating source (3) and are embodied normally as wire antennas, horn antennas or the like. In particular for HPM active systems (1) to be conveyed, the antenna aperture of the antenna (4) is limited by the geometric edge dimensions of a carrier system (2) for the HPM active system (1), which further leads to a reduction in the efficiency of the antenna (4). According to the present invention, the antenna (4) is integrated into an airbag (5) that is inflated for operational use and thereby simulate the antenna (4). The antenna airbag (5) is inflated near a target (100) onto which at least one pulse (8) must be radiated.

  • Patent number: 6794831
    Abstract: A system for and method of generating electromagnetic radiation in which the radiation has both a first and second utility. The electromagnetic radiation is modulated to produce electronically detectable variations to achieve the second utility, the variations not affecting the first utility. In one embodiment, the electromagnetic radiation is visible light. In this embodiment, the first utility is illumination and the second utility is the transmission of data. In another embodiment, the invention provides a lamp for generating visible light capable of providing illumination and transmitting data to a receiver. Any variations in the visible light resulting from the data transmission are imperceptible by a human eye regardless of the nature of the data being transmitted. In yet another embodiment, a power line carrier modem may be used with the present invention to transmit information to the source.

  • Patent number: 6777884
    Abstract: An electroluminescent lamp or display comprises a first electrode on a substrate interdigitated with a second electrode on the same substrate. A layer of electroluminescent material is provided over the electrodes. The arrangement has the advantage that light from the electroluminescent material does not need to pass through either of the electrodes. The substrate may be a printed circuit board. In an alternative embodiment the second electrode is provided over the layer of electroluminescent material and gaps are provided in the electrode for the emission for light. The electroluminescent lamps may be used to form a seven-segment display.

  • Patent number: 6777882
    Abstract: G2 electrode is mounted so as to be movable along the beam line and, optionally, perpendicular to it as well. G1 and G2 are curved with a constant gap between G1 and G2 in the radial direction (so that the two electrodes are concentric). This contrasts with the prior art where G1 and G2 were equidistantly spaced along the beam line direction instead. G1 is made re-entrant adjacent the slit so as to improve extraction efficiency from the plasma. Finally, a lens such as a quadrupole lens is formed downstream of G3.

  • Patent number: 6774858
    Abstract: A folded monopole antenna uses two vertical monopole antenna elements one of which is tapered and resistively loaded to a ground plane. The tapered vertical monopole antenna element includes a series of operably coupled cylindrical sections that extend from a base end of this element to its top end. The cylindrical sections decrease in diameter from the base end to the top end of this element. The second monopole antenna element has a substantially constant outer diameter. An antenna feed is coupled to this second element. A third antenna element of substantially equivalent diameter to the second element is operably coupled to the top ends of the first and second antenna elements. In both transmitting and receiving modes, the tapered monopole antenna element is considered to cause a cancellation of the electric field from the feeding antenna element and thereby provide a wide range of impedance matching.

  • Patent number: 6774851
    Abstract: The present invention relates to a reflectarray antenna. The reflectarray antenna comprises a dielectric substrate layer disposed on a ground plane. An array of radiating elements such as microstrip patches of similar size are arranged into a regular lattice configuration on the top surface of the substrate layer. A periodic configuration of slots of variable size are provided at the bottom surface of the substrate layer. A required phase shift at each position on the reflectarray surface is obtained by adjusting the slot length on the ground plane. The incident wave from the feed excites the dominant mode on the microstrip patches The presence of slots acts as an inductive loading of the patches, which introduces a phase shift in the patch response. The inductance of each slot depends on its length.
