A sandwich structure with fractal pattern for microstrip line is proposed, in which a fractal pattern consisting of “H” is etched in the plane between the microstrip line and the ground plane of microstrip line. The transmission characteristics of that sandwich structure appear to have the multiple gaps and pass bands of electromagnetic waves is from 40 MHz to 10 GHz, and in particular the use of the fractal patterns array is increasing the gaps property of the gaps and pass bands. In this article, the transmission characteristics of one microstrip line with the sandwich structure normalized by 50 Ω are directly calculated by the finite different time domain (FDTD) method. Experimental observations are in good agreement with the result of FDTD simulations. Microstrip transmission lines incorporating a sandwich structure with fractal patterns exhibit band‐stops and slow‐wave characteristics, which can be exploited to reject unwanted frequency and to reduce the dimensions of the microstrip structure. © 2006 Wiley Periodicals, Inc.
