Abstract

Using microstrip technology, a novel metamaterial unit cell is presented. The metamaterial unit cell consists of microstrip gaps and via hole whose behavior is equivalent to the combination of series capacitors and shunt inductors, respectively. A new chamfered band structure bandpass filter is designed and fabricated using the presented metamaterial unit cell. The transmission loss S~21~ and return losses S~11~ of the proposed bandpass filter are equal to −0.41 and −25.5 dB, respectively. The experimental and simulation results closely correspond to each other. © 2007 Wiley Periodicals, Inc.
