Novel compact microstrip resonators consisting of multiple 2D Hilbert prefractal curves are presented. Proposed resonators use fractal curves of the 3 rd and 4 th orders to achieve length reduction of over 64% and 81%, respectively, when compared to the conventional capacitively coupled resonators tuned to the same frequency. A configuration with fractal curves of the 3 rd order, fabricated in standard PCB technology, exhibits improvement of unloaded Q ‐factor within range from 15% to 90%, depending on the resonant frequency. © 2005 Wiley Periodicals, Inc.
