Claim:
1. A system for communication comprising a transmitter for transmitting data, the transmitter comprising: a transmitter circuit; and a transmitting array antenna; the transmitting array antenna comprising a plurality of transmitting antenna elements, the transmitter circuit comprising a plurality of outputs, each of the plurality of outputs being connected to a corresponding one of the plurality of transmitting antenna elements, the transmitter circuit comprising a first channel and a second channel, each of the first channel and the second channel comprising a modulator for modulating a data stream onto a carrier signal, the transmitter circuit and the transmitting array antenna being configured to transmit: the first RF beam and the second RF beam being superimposed on each other, the first RF beam being comprised of a first rotational state having helical spiral surfaces of constant phase, and the second RF beam being comprised of a second rotational state having helical spiral surfaces of constant phase, the helical spiral surfaces of constant phase of the first rotational state being different from the helical spiral surfaces of constant phase of the second rotational state, wherein the transmitting array antenna comprises 2M+1 transmitting antenna elements, M being a positive integer, and wherein the transmitting antenna elements are arranged at equal spacing in a circular pattern, and wherein the first rotational state is associated with a state number M wherein N i is the number of the transmitting antenna element and N=2M+1 is the number of transmitting antenna elements.
