Abstract: A turnstile antenna element and balun for use in a phased array are described. The antenna includes a plurality of stacked bowtie radiators. Each stacked bowtie radiator includes a driven conductor and a passive conductor separated by a dielectric. The balun includes a central member having dielectric slabs symmetrically disposed on external surfaces thereof. At least one end of the balun is provided having a shape such that conductors on the dielectric slabs of the balun can be coupled to the driven radiator conductors.

Abstract: Phased array antenna systems with antenna elements having substrates with varying dielectric constants selected to reduce the self-return signal of corner elements in the array. In one example, a phase array antenna system includes a plurality of stacked-patch microstrip antenna elements arranged in a two-dimensional array, each stacked-patch microstrip antenna element of the plurality of stacked-patch microstrip antenna elements including a pair of conductive patches disposed above a ground plane on a dielectric substrate. The dielectric substrate of corner stacked-patch microstrip antenna elements in the array has a dielectric constant lower than a dielectric constant of the dielectric substrate of non-corner stacked-patch microstrip antenna elements in the array.
