Abstract
A phased array system having antennas, non-variable phase shifters, and switches. The non-variable phase shifters are configured to be coupled selectively to a transmitter or a receiver. A non-variable phase shifter is configured to shift a phase of an electromagnetic energy wave that traverses the non-variable phase shifter by a fraction of a period of the electromagnetic energy wave for a range of frequencies of the electromagnetic energy wave. At least one of the fraction and the range associated with the non-variable phase shifter is different from at least one of the fraction and the range associated with other non-variable phase shifters. The switches are configured to couple selectively the antennas to the non-variable phase shifters, the transmitter, or the receiver.
