Abstract

A multiband filter for the microwave frequency band, designed for antenna feeders and sensor applications is presented. The structure comprises a 2D periodically patterned surface sandwiched between two dielectric layers and two parallel metal planes. The frequency properties are derived by computing dispersion diagrams through full-wave electromagnetic simulation. Some of the frequency pass-bands are narrow enough to allow selective applications. A parametric study is performed in order to facilitate application specific design.
