  • Patent number: 11688922
    Abstract: A color changing television antenna with LED includes a casing, an antenna radiator in the casing, a coaxial cable situated at a rear end of the casing and connected to the antenna radiator. The casing contains an LED lamp, and a transparent display panel extending to the outside from the display panel. The part of the display panel inside the casing has a receiving slot for installing the LED lamp and allowing the LED lamp to project light onto a sidewall of the receiving slot. The display panel transmits the projected light by total reflection. A reflector is installed on a surface of the display panel for reflecting the light transmitted inside the display panel and forming a predetermined pattern. This television antenna can display a specific pattern and improve the display effect based on the principle of total reflection of the transparent display panel.

  • Patent number: 11600929
    Abstract: The present invention is a unique process of manufacturing rigid members with precise “shape keeping” properties and with reflective properties pertaining to radio frequency energy, so that air, land, sea and space devices or vehicles may be constructed including parabolic reflectors formed without discrete permanent layering. Rather, such parabolic reflectors or similarly, vehicles, may be formed by homogeneous construction where discrete layering is absent, and where energy reflectivity or scattering characteristics are embedded within the homogeneous mixture of carbon nanotubes and associated graphite powders and epoxy, resins and hardeners. The mixture of carbon graphite nanofiber and carbon nanotubes generates higher electrode conductivity and magnetized attraction through molecular polarization. In effect, the rigid members may be tuned based on the application.

  • Patent number: 8009120
    Abstract: Antennas using nonwoven geotextiles with embedded metallic or other wave carrying fibers are described herein. The geotextiles antennas are designed to be an internal, integral part of the nation's infrastructure. Geotextile antennas are flexible and easily conform to natural and manmade surfaces such as exterior building surfaces, for example, roads, roofs and bridges. Geotextile antennas are considerably less vulnerable to damage and probably much less expensive than the current, highly vulnerable and costly cell towers. In particular, geotextiles used in roads are especially well protected by the asphalt pavement above. The fabric-based conformal antenna enhances the usefulness and reliability of the communication infrastructure which is exceedingly vulnerable to vandalism, terrorism and natural disasters.

  • Patent number: 7965488
    Abstract: An antenna is disclosed to efficiently ionize the atmosphere for the purpose of reducing the aerosol counts, and therefore the number of poluted particles in suspension in the atmosphere, by deposition to ground. The antenna includes peripheral nodes and a central node. Each of the peripheral nodes is connected to adjacent peripheral nodes through peripheral spokes. The peripheral nodes are also connected to the central node through radial spokes. Electric power is applied to the peripheral spokes and the radial spokes causing the antenna to charge the atmosphere through the emission of ions. The antenna minimizes an attenuation factor that reduces ionization efficiency and reduces the land requirements for its installation.

  • Patent number: 7956818
    Abstract: An leaky coaxial cable antenna with high radiation efficiency and low insertion loss is described. The outer shield of the coaxial cable is constructed to facilitate energy transfer between the bifilar mode and the monofilar mode by constructing the outer conductor of a first conductive strip wrapped in a spiral about the dielectric and a plurality of second conductive strips wrapped in a counter spiral about the first but spaced serially along the length of the coaxial cable such that portions of the cable are wrapped by a single spiral and the other portions are wrapped by two spirals.

  • Patent number: 7944401
    Abstract: A radiating element made from a conductive-nonwoven web is incorporated into a signal emitting apparatus. The signal emitting apparatus, for instance, may comprise an RFID tag. The conductive-nonwoven web contains, in one embodiment, conductive fibers combined with pulp fibers. The conductive fibers may comprise carbon fibers. The nonwoven web may be made using a conventional paper-making process. The resulting conductive web is not only well suited for use as an antenna, but is also relatively inexpensive to manufacture and can be easily incorporated into numerous products.
