Stacked bowtie radiator with integrated balun

摘要

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.

1. An integrated antenna element comprising:
a. an antenna element comprising:
i. a dielectric substrate having a generally pyramidal shape with a feed point provided at the center, the substrate having an inner surface and an outer surface;ii. at least two inner conductors disposed over the inner surface of the substrate, each of the inner conductors having a generally triangular shape with one vertex terminating proximate the feed point; andiii. at least two outer conductors disposed over the outer surface of said substrate, each of the outer conductors opposite to at least one inner conductor.
