摘要：
A microstrip bandpass filter using a dual-spiral configuration is proposed. Unlike conventional filter topology, this filter is integrated directly within 50 Omega microstrip lines. The filter has a simple configuration, and compact size, and is easy to fabricate. Two transmission zeros close to the passband improve the selectivity of the filter. A demonstration filter is designed and examined, and the theoretical and experimental results are presented. (c) 2005 Wiley Periodicals, Inc.
