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.
