Abstract
A phased array system has a substrate, a plurality of elements, a beamforming IC, and a plurality of feedlines electrically coupling the plurality of elements with at least one beamforming IC. In preferred embodiments, the feedlines are non-intersecting, symmetric feedlines that mitigate cross-polarization.
Claims18
A phased array system comprising:
- a substrate;
- a plurality of dual-mode receive and transmit elements configured in a triangular lattice on the substrate, wherein the plurality of dual-mode receive and transmit elements are arranged in a slant polarization split feed configuration;
- a beamforming integrated circuit (IC) on the substrate, the beamforming IC comprising a first set of dual-mode receive and transmit element interfaces configured to be polarized in a first polarization and a second set of dual-mode receive and transmit element interfaces configured to be polarized in a second polarization different than the first polarization;
- and
- a plurality of feedlines electrically coupling the plurality of dual-mode receive and transmit elements with the beamforming IC,
- wherein the plurality of dual-mode receive and transmit elements comprise a first element and a second element that is adjacent to the first element, each of the first and second elements comprising a positive polarization interface and a negative polarization interface, and
- wherein the first element and the second element are offset by a physical distance such that the positive and negative polarization interfaces of the first element and the second element are collinear.
