  • Planar array with radiators adjacent and above a spiral feeder
    Patent number: 5327146
    Abstract: A dipole array antenna includes a conducting substrate, a feeder layer, and a dipole layer. The feeder layer is spirally formed by etching a first thin film on the foamed dielectric layer. The feeder layer is placed on a conducting substrate and a connector is attached to the feeder layer. The dipole layer is placed on a second foamed dielectric layer deposited on the feeder layer so as to prevent the energy loss of the feeder layer by etching a second thin film.
