  • Highly isolated dual compact stacked spiral antenna
    Patent number: 6300919
    Abstract: An antenna is described which includes a plurality of antennas stacked on top of each other in a compact cavity. Input match and radiation gain can be enhanced by the application of a capacitor and inductor in the feed of the spiral lowest in the cavity. The antenna can fit into a very compact space while providing circular polarization over the desired bands of the antennas that are isolated.

  • Compact spiral antenna
    Patent number: 5990849
    Abstract: An antenna is provided that receives electromagnetic radiation and includes a dielectric substrate (106). First and second spirals (60 and 70) on a first surface of the substrate (106) radiate the electromagnetic radiation. A third spiral (80) is utilized on a second surface of the substrate (106) and is substantially underneath one of the first and second spiras(60 and 70). The resulting spiral antenna is compact and has multioctave bandwidth capability.
