Abstract

A novel ultra‐wideband (UWB) bandpass filter with a compact size is proposed. By using a two‐layered substrate configuration and an H‐shaped slot on the ground, a vertical‐coupled microstrip resonator structure is formed. Three resonant peaks of the proposed structure are extracted around the lower end, the center, and the upper end of the UWB passband. The compact two‐layered filter has an overall length of about a half guided wavelength at the center UWB frequency and exhibits promising performance for UWB applications. © 2007 Wiley Periodicals, Inc.
