  • Patent number: 10103444
    Abstract: An antenna array includes a plurality of ½ flared notch radiators recessed within a missile nose cone and positioned in a circumferential arrangement around and extending radially from the payload's metal skin to contact an annular metal cover that provides a ground plane such that each ½ flared notch radiator is inclined towards the boresight axis. The payload's metal skin provides an image plane for each ½ flared notch radiator to launch RF energy with a radial polarization normal to the image plane forward through the annular RF radome. Each ½ flared notch radiator may be positioned within a 5½ sided waveguide to further improve directionality and isolation.

  • Patent number: 10033099
    Abstract: A spacecraft communications payload includes a beam forming network (BFN), wherein the BFN includes a first feed waveguide and a first set of branch waveguides, each branch waveguide in the first set operating in a frequency band having a characteristic waveguide wavelength ?g1. A proximal portion of the first set of branch waveguides is communicatively coupled with the first feed waveguide. A distal portion of the first set of branch waveguides is communicatively coupled by way of an array of slots with a plurality of radiating elements. A separation distance between adjacent slots in the array is approximately equal to ?g, and the array of slots is configured as a honeycomb-like triaxial lattice. In some implementations, a compact BFN may be configured to simultaneously operate at two different polarizations (“dual-polarized”) and/or frequency bands (“dual-band”).
