A motor vehicle antenna pane with improved diversity andor multiband applicability in the VHF range for mounting in a metal surround provided with a conductive panel spaced from the metal surround such that an elongated dielectric slot is produced between the two. The creation of islands of polymer material of refractive index n1 completely surrounded by polymer material with refractive index n2 where n1 has a higher index than n2 allows the islands of n1 indexed polymer to serve as optical waveguides. The first and second resonators are designed so that the first resonator is most efficient at a high frequency while the second resonator has maximum response at a low frequency. Therefore, much more electric charges can be stored in the storage capacitor.
