Self-steering antenna array

A method for receiving and transmitting electromagnetic signals, comprising the steps of:

• receiving an electromagnetic signal utilizing a plurality of antennas, each one of said plurality of antennas having an axis generally oriented in the azimuthal plane and having a first end coupled to a respective one of a plurality of control means for controlling said one of said plurality of antennas, said control means positioned between two additional control means along an arc to form a centralized channel having a longitudinal axis perpendicular to said axes of said plurality of antennas, each one of said plurality of antennas having a second end pointing radially outward from said centralized channel, each antenna operating independently from each other and each pointing in a different generally azimuthal direction and having a narrow antenna beam pointing generally in the respective azimuthal direction, wherein 3600 of azimuthal coverage is provided with all of the beams;
• determining a signal strength of the electromagnetic signal received at each of the plurality of antennas;
• comparing the determined signal strengths and determining which of the antennas is receiving the strongest signal;
• and
• switching the received electromagnetic signal and signals to be transmitted based on the comparison performed by said comparing step to select the one of said plurality of antennas receiving the strongest signal by transmitting a switching signal to the selected antenna via the centralized channel for receiving and transmitting the electromagnetic signals.

A communication system having at least one self-steering antenna array, said self-steering antenna array comprising:

• a plurality of antennas each having an axis generally oriented in the azimuthal plane and having a first end in a common centralized region forming a centralized channel and a second end pointing radially outward from said centralized channel, the second ends of the antennas generally pointing in different azimuthal directions from one another, each antenna operating independently from the other antennas and operative to receive and emit electromagnetic signals within a narrow beam pointing generally in the respective azimuthal direction;
• at least one receiver for processing the received electromagnetic signals and for providing signal quality information of the electromagnetic signal received by each antenna;
• comparison circuitry for comparing the signal quality information provided by each receiver, and determining which of the antennas is receiving the highest quality electromagnetic signal;
• and
• switching circuitry for switching the received electromagnetic signals and the signals to be emitted, based on the comparison performed by the comparison circuitry, the switching circuitry selecting one of the plurality of antennas by transmitting a switching signal to the selected antenna via said centralized channel to emit and receive the electromagnetic signals based on the comparisons
