Estudio del comportamiento de una línea microstrip en presencia de estructuras EBG tipo cruz

In this work, the existence of electromagnetic bandgaps (EBG) on microstrip transmission lines by including crossshaped structures are studied in the frequency range of 8-15 GHz and compared with mushrooms type structures. The results show that the new structure behaves as a medium EBG and presents some advantages over mushroom inclusions, such us a double band-gap in the frequency range under study, which is related with its capacitive impedance. Furthermore, the incorporation of more than one row of cross-shaped elements on either side of the microstrip line does not significantly varies the results obtained using a single row, which allows more compact designs.Ingeniería, Industria y Construcció
