Abstract
Described is a generally planar antenna having a tapered array of radiating/receiving elements that are transversely mounted in capacitive coupling to an elongated transmission line that underlies the array. The shorter dipole elements resonate at high frequencies, the longer dipole elements resonate at lower frequencies, and the intermediate length dipole elements resonate at intermediate frequencies. The dipole elements are mounted on one surface of a planar dielectric substrate to form a planar, generally triangular shaped pattern having relatively narrow spacing between individual dipole elements (for example, one-twentieth of the wavelength of the intermediate frequencies), and having a relatively large spacing to width ratio. Coupling between the dipole elements causes then to operate as if they were a single broadband dipole element.
