Abstract

Methods and apparatus for an electrically steered array including a phased array aperture having a plurality of elements at a selected spacing, the aperture to provide up to four simultaneous, independent beam sets, wherein the elements are controlled by a single complex weight.

Claims

1. An electrically steered array, comprising:

a phased array aperture having a plurality of elements at a selected spacing, the aperture to provide up to four simultaneous, independent beam sets, wherein the elements are controlled by a single complex weight.

2. The array according to claim 1, wherein the array forms a part of a communications on the move system.
