  • Patent number: 5844523
    Abstract: Electromagnetic and electrical apparatuses use a laminate structure having a thermoplastic elastomer with variable dielectric loss as a dielectric layer. A conductive layer laminated to the thermoplastic elastomer allow use for applications such as printed circuit boards and slot antennas. Additional conductive and dielectric layers still allow use as a printed circuit board as well as other antenna structures. Some embodiments of the apparatuses disclosed exhibit many desired properties, such as flexibility, conformability and weatherability.

  • Patent number: 4073417
    Abstract: Disclosed is a unitary bracket for holding down an antenna mounted on a vehicle. The bracket includes an elongate body portion having one end configured to be readily clipped onto the gutter strip of the vehicle. The other end of the body portion is configured to receive and hold the antenna in a position generally paralleling the roof line of the vehicle. Because different styles of vehicles have different sized gutter strips, the end of the body portion which is clipped onto the strip can be made universally adaptable to the various sized strips.
