Phased array systems
First Claim
1. A phased array system, comprising:
- a first antenna;
a second antenna;
a first phase shifter configured to be coupled selectively to a transmitter and to be coupled selectively to a receiver; and
a switch configured to couple selectively the first antenna to the first phase shifter, to couple selectively the first antenna to the transmitter, to couple selectively the first antenna to the receiver, to couple selectively the second antenna to the first phase shifter, to couple selectively the second antenna to the transmitter, to couple selectively the second antenna to the receiver, and to cause selectively an open circuit between the first antenna and the first phase shifter and between the second antenna and the first phase shifter.

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.
