  • Patent number: 5829121
    Abstract: Single and multiple radiator element planar array antennas and a method of making are disclosed. A styrofoam dielectric substrate, a die cut conductive first layer, preferably copper foil, secured to one surface and a conductive second layer, preferably aluminum foil, on the other surface forms the ground plane. A cutting die of cutting blades in a required array on a cutting press is used to cut through the conductive layer and into the dielectric layer in a sandwich of the two to provide inexpensive, durable and dimensionally stable antennas.

  • Patent number: 5793336
    Abstract: A conformal antenna assembly disclosed has a first antenna portion sensitive to a UHF band of frequencies. A thin, flat, low-profile, weather-resistant housing encloses the first antenna portion. The housing has a conformal back surface that conforms to the shape of a support surface on which said housing is mounted. The housing has an arrangement to mount the housing to a support surface. In one form the housing is flat to mount on the side of a building and in another form is double curved to mount on the back of a satellite dish. A coaxial cable has a center conductor and a tubular outer conductor with an insulator between the conductors. The center conductor and outer conductor are connected at one end to the first antenna portion. The inner conductor terminates at the other end in an end terminal to conduct signals from the first antenna portion to the end terminal.
