MULTI-BAND FILTER BUILT WITH A PERIODICALLY PATTERNED STRIPLINE

摘要

A novel unit cell consisting of a meander shaped metallic patch, positioned in between two dielectric grounded layers and connected to one of them by three vias is proposed. The large number of reactive elements composing the structure are shown to determine an equally large number of electromagnetic band-gaps making the structure appropriate for advanced sensor or multi-band filtering applications in modern wireless systems. Parametric studies considering the value of the dielectric constant of one of the dielectric layers, for two orthogonal directions of propagation are reported.
