  • Patent number: 8779995
    Abstract: This high-frequency waveguide is formed by first and second conductors disposed opposite each other at a spacing of ?0/2, where ?0 is the free space wavelength of the operating frequency of a high-frequency signal. A ridge is provided at the waveguide formation portion between these first and second conductors, which protrudes from one of the first and second conductors toward the other and is formed extending along the waveguide formation portion. A plurality of columnar protrusions with a height of ?0/4 are disposed at a spacing of less than ?0/2 to at least one of the first and second conductors on the outside of the waveguide formation portion and to the outside of the ridge.

  • Publication number: 20140085148
    Abstract: The present invention is a method and apparatus for receiving and converting incident radiation into DC current. The method begins with selection of an antenna having a terminal tip with a sharp edge. The antenna is layered with a substrate and a first coating. A first electrode and a metallic/mCNT antenna are layered on the first coating, and a plasmonic layer is then added. A gap is formed which is bounded on one side by the terminal ends of the plasmonic layer and the first coating, and a second electrode and a second coating on the other. The second electrode is layered upon the second coating which is layered upon the substrate. A set of AC currents is induced along the length of the antenna. The method then calculates whether or not the induced AC currents are large enough to create voltages for field emission. If the voltages are large enough, then a forward bias and a reverse bias are initiated.

  • Patent number: RE44047
    Abstract: A wireless transceiver including multiple antennas, an antenna switch, and a media access controller that controls the antenna switch for determining when to switch to another antenna based on packet error rate (PER). Instead of switching the antenna on a packet-by-packet basis, antenna selection is made after one or more packets errors have been detected. The CRC is used to identify receive packet errors. A timer is used to determine each transmit packet error when an acknowledge packet is not received in time. A method of selecting from among multiple antennas including counting packet errors, comparing a packet error count with a threshold value to determine a threshold condition, switching to a different antenna if the threshold condition is met, and resetting the packet error count when the threshold condition is met.
