Abstract
An antenna array includes a plurality of apertures arranged within a uniform lattice and adapted to radiate at least two beams in different frequency bands in arbitrary pointing directions. A first aperture group and a second aperture group of the plurality of apertures are adapted to radiate a first beam and a second beam of the at least two beams, respectively. The first aperture group and the second aperture group are substantially coextensive, and the apertures of each of the first and second aperture groups are aperiodically distributed among the uniform lattice.

An antenna array comprising:
- a plurality of apertures arranged at a uniform lattice and adapted to radiate at least two beams in different frequency bands, wherein:
- a first aperture group and a second aperture group of the plurality of apertures are adapted to radiate a first beam and a second beam of the at least two beams, respectively;
- the first aperture group, and the second aperture group are substantially coextensive;
- and
- the apertures of each of the first and second aperture groups are aperiodically distributed among the periodic lattice.
A method of operating an antenna array comprising a plurality of apertures arranged at a uniform lattice, the method comprising:
- radiating a first beam at a first frequency band using a first aperture group of the plurality of apertures;
- and
- radiating a second beam rat a second frequency band using a second aperture group of the plurality of apertures,
- wherein the first aperture group and the second aperture group are substantially coextensive, and the apertures of each of the first and second aperture groups are aperiodically distributed among the periodic lattice.
An antenna array comprising:
- a first group of apertures adapted to radiate a first beam at a first frequency;
- and
- a second group of apertures adapted to radiate a second beam at a second frequency, the first beam and the second beam being radiated simultaneously,
- wherein the first aperture group and the second aperture group are substantially coextensive and are aperiodically distributed among a uniform lattice of the antenna array.
