  • Hooked stub collinear array antenna
    Patent number: 7098861
    Abstract: A hooked stub collinear array antenna formed from a single conductor. The antenna operates at a design frequency having an associated wavelength. The antenna includes a plurality of radiating elements that are substantially one half the wavelength. The radiating elements are aligned with a longitudinal axis of the antenna. The antenna further includes a delay element connected between each of the plurality of radiating elements. The delay element is aligned with a transverse axis approximately ninety degrees from the longitudinal axis. The delay element extends approximately one quarter of the wavelength from the longitudinal axis and adjacent delay elements of a plurality of delay elements are sequentially rotated at 90 degree intervals relative to each other about the longitudinal axis. The total length of the delay element is approximately one half the wavelength.
