Multiband antennas can simplify considerably the complexity of receivers and transmitters,
reducing the size and the mass of the conventional configurations. On the other hand, applications with
high directivity requirements need array designs to comply with the directivity specifications using
conventional technology. EBG superstrate designs have been satisfactory applied to single band
applications using a single EBG superstrate layer. The number of number of radiating elements of
conventional technology designs are considerably reduced when using EBG technology. Dual band
configurations have also been designed in a single layer, but when working frequencies are too close a
second EBG layer is needed.
A dual layer EBG superstrate which can easily be adjusted to the desired operational frequencies is
presented. The design has been realized to comply with the navigation antenna requirements of Wide
Area Augmentation system (WAAS) application in L1 and L2 bands.
