Abstract :
In this paper the use of via-holes in microstrip lines to design periodic structures that can be regarded as metallodielectric electromagnetic crystals is analyzed. The proposed novel periodic structures achieve a notably increased reflectivity compared to that obtained with a single via-hole. Theoretical analysis and experimental results are provided showing a satisfactory performance for these devices as broadband reflectors or short-circuits with enhanced behavior at high frequencies
