Vol: 57(71) No: 3 / September 2012 Band Structure of a Multi-Via Periodic Strip-line Surface Devised for Multiple Band Rejection Applications Aldo De Sabata Department of Measurements and Optical Electronics, \"Politehnica\" University of Timişoara, Faculty of Electronics and Telecommunications, Bd.

The device relies upon a periodically patterned surface impressed on one side of a microstrip board and connected to the ground plane by several vias and covered with a dielectric material and a second metal plane. The assessment of the properties of the structure, which presents several electromagnetic band-gaps, is performed by calculating the dispersion diagrams through full-wave electromagnetic simulation. The design of the spatial period of the surface is flexible. It is shown that the proposed device can be designed to meet applications dependent frequency domain requirements by scaling.
