Periodic microstrip‐line electromagnetic band‐gap (EBG) structures with improved bandstop behaviors are constituted by adding the backside aperture and widening the strip conductor regarding to the low‐ and high‐impedance microstrip‐line sections, respectively. Its characteristics are studied by using the finite‐difference time‐domain (FDTD) method. After our FDTD‐derived results are independently verified by those from ADS for an initial EBG structure, extensive work is done to investigate the concerned bandstop behaviors versus strip/aperture widths and lengths in order to achieve a broadened and deepened frequency stopband. © 2004 Wiley Periodicals, Inc.
