Title:
SPARSE PHASE-MODE PLANAR FEED FOR CIRCULAR ARRAYS
Document Type and Number:
WIPO Patent Application WO/2016/169323
Kind Code:
A1
Abstract:
System and apparatus embodiments are provided for sparse phase-mode planar feed for circular arrays of transducing elements for a beam-steering antenna system. In an embodiment, a sparse phase-mode feed for an array of antenna elements includes an electrically conducting first disk; an electrically conducting second disk parallel to and coaxial with the first disk; an electrically conducting outer wall; a plurality of phase-mode feed probes, wherein at least a portion of the phase-mode feed probes are electrically coupled to the first disk, and wherein the phase-mode feed probes are symmetrically arranged around the center of the first disk; and antenna-element probes, wherein at least a portion of the antenna-element probes are electrically coupled to the second disk, and wherein the antenna-element probes are symmetrically arranged on an outer portion of the second disk, wherein the number of phase-mode feed probes is less than the number of antenna element probes.
