  • Tulip antenna with tuning stub
    Patent number: 7791554
    Abstract: The tulip antenna has two orthogonally intersecting conductive plates. Each intersecting plate has two ends, and one of these ends is smoothly tapered. The intersecting plates intersect such that the tapered end of both plates together form a tapered side when the intersecting plates intersect. An inner conductor of a coaxial cable is connected to the two intersecting plates at the tapered side of the intersecting plates. The inner conductor and the surrounding insulator pass through a tuning stub and then through a metallic ground plate. The tuning stub is connected to the ground plate. An aperture in the ground plate is sized such that the insulator can pass through it, just as the insulator can pass through the tuning stub. The tuning stub increases the upper frequency limit over which the antenna operates. The outer conductor of the coaxial cable is attached to the ground plate.
