Abstract

A sandwich structure with fractal pattern for microstrip line is proposed, in which a fractal pattern consisting of β€œH” 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 Ξ© 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.

We propose modifying the spectral-domain approach to analyze planar lines with a very thin copper strip, presenting a fractal character. We derive, from a fractional derivative electromagnetism formulation, a new modified surface impedance introduced in that numerical technique. The results exhibit

## Abstract A novel miniature antenna loaded with a space‐filling shaped transmission line is presented. Return loss and antenna gain results are compared with a traditional square patch. Experimental results show that the antenna presents an electrical area 18 times less than the square patch. Β© 2
