Abstract
In one aspect, the inventive concepts disclosed herein are directed to an antenna array system employing a current sheet array (CSA) wavelength scaled aperture. The CSA wavelength scaled aperture can include a first frequency region associated with a first operating frequency band and a second frequency region associated with a second operating frequency band. The first operating frequency band can include one or more current sheet sub-arrays having a respective plurality of first unit cells scaled to support the first operating frequency band. The second operating frequency band can include one or more current sheet sub-arrays having a respective plurality of second unit cells scaled to support the second operating frequency band. The CSA wavelength scaled aperture can include one or more capacitors each of which coupled to a respective first unit cell of the first frequency region and a respective second unit cell of the second frequency region.
