An antenna array is provided including a substrate, a metal ground plane proximate the substrate, and a dielectric layer proximate the metal ground plane. A first plurality of antenna elements including polaronic organic transducer elements is proximate the dielectric layer and connected in series. A second plurality of antenna elements including polaronic organic transducer elements is proximate the dielectric layer and also connected in series. The first and second plurality of antenna elements are electrically isolated. The antenna elements of the first plurality of antenna elements are configured to detect a first wavelength, while the antenna elements of the second plurality of antenna elements are configured to detect a second wavelength, different from the first wavelength.
