Abstract
An antenna array can include multiple radiating cells, each comprising a radiating element and a phase shifter. Further, each radiating element can comprise a first radiating element port and a second radiating element port. Each of the radiating cells can be configured to selectively connect the phase shifter to one of the radiating element ports. Each of the radiating cells can further comprise a phase delay difference between the signal paths associated with the radiating element ports. Further, the radiating cells can have physical polarization orientations that can be different from at least one other radiating cell.

(canceled)
An antenna array comprising:
- a plurality of radiating cells to produce a beam having a particular orientation of a linearly polarized field, the plurality of radiating cells comprising:
- a first radiating cell to selectively generate one of a first pair of phase states of the linearly polarized field, the first radiating cell comprising a first single-bit phase shifter selectively coupled to one of first and second element ports of a first dual linear polarized radiating element via a first switch, and having a first phase delay difference between signal paths associated with the first and second element ports;
- and
- a second radiating cell to selectively generate one of a second pair of phase states of the linearly polarized field, wherein the second pair of phase states is different than the first pair of phase states, the second radiating cell comprising a second single-bit phase shifter selectively coupled to one of third and fourth element ports of a second dual linear polarized radiating element via a second switch, and having a second phase delay difference between signal paths associated with the first and second element ports.
