摘要：

This article presents a novel ultra-wideband bandpass filter with controllable notched bands, compact size, and relaxed fabrication requirements. Its implementation is based on a rectangular slot ring resonator with an embedded S-shaped slotline. The behavior of the rectangular slot ring resonator is characterized and subsequently adopted to build the wide passband. The notched band necessary for rejecting wireless local-area network (WLAN) signals is implemented by the S-shaped slotline. A prototype filter is implemented based on the proposed structure and good agreement is found between simulations and measurements. (C) 2010 Wiley Periodicals, Inc.
