Abstract: An electronically scanned antenna array (ESA) includes a first band including first antennas and a second band including second antennas. Each first antenna operates over a first frequency bandwidth from a first frequency to a second frequency. At least two adjacent first antennas are spaced from one another by a first value of a wavelength scale parameter that corresponds to the second frequency. Each second antenna operates over a second frequency bandwidth from the first frequency to a third frequency greater than the first and less than the second frequency. At least two adjacent second antennas are spaced from one another by a second value of the wavelength scale parameter that corresponds to the third frequency. A second subset of the plurality of second antennas is adjacent to a first subset of the plurality of first antennas and spaced from the first subset based on the wavelength scale parameter.

Abstract: A communication system is disclosed. In embodiments, the communication system includes an electronically scanned array (ESA) including a plurality of antenna terminal elements, the ESA configured to transmit an output beam. In embodiments, the communication system may further include a phase shift network. The phase shift network may include: a first set of one or more tunable local oscillators; a first antenna array configured to generate a first intermediate phase shift signal; and a second antenna array configured to generate a second intermediate phase shift signal. In embodiments, the phase shift network further includes a first plurality of mixers configured to combine an intermediate transmit signal and at least one of the first intermediate phase shift signal or the second intermediate phase shift signal to generate ESA input signals, wherein the ESA is configured generate the output beam in response to the ESA input signals.
