CPC H01Q 21/12 (2013.01) [H01Q 1/246 (2013.01); H01Q 3/40 (2013.01); H01Q 11/14 (2013.01)] | 33 Claims |
1. An antenna system comprising:
an array of antennas disposed in a predetermined non-linear pattern, the array of antennas comprising a plurality of antennas and having a two-dimensional field of view; and
a two-dimensional beamforming network (BFN) disposed entirely on a single first surface, and having a one-dimensional array-side interface disposed on the first surface and a one-dimensional beam-side interface disposed on the first surface; wherein:
the antennas of the array of antennas are individually communicably coupled to the array-side interface, such that segments of the beam-side interface map to respective pixels in the two-dimensional field of view;
the predetermined non-linear pattern defines a second surface;
the array of antennas comprises a plurality of disjoint sets of antennas;
each disjoint set of antennas comprises a plurality of antennas of the array of antennas; and
for each disjoint set of antennas, each antenna of at least a non-empty subset of the disjoint set of antennas is perpendicularly displaced a respective distance along the second surface from a longitudinal axis of a hypothetical linear array of antennas disposed on the second surface.
