Abstract

A novel fractal‐shaped compact microstrip resonant cell (CMRC) featuring a strong slow‐wave effect has been presented. Its vital usefulness in the process of microstrip line miniaturisation has been proved and experimentally validated on the basis of a compact 3‐dB branch‐line coupler illustrating the possibilities of the approach. A prototype example structure has been designed to mirror the characteristics of a conventional device, simultaneously presenting substantial size reduction. The measured results are in excellent accordance with theoretical characteristics confirming the utility of proposed novel fractal‐shaped CMRC in compact circuits developed in microstrip technology. © 2010 Wiley Periodicals, Inc.
