Design of a Wide Stopband Bandpass Filter with Source-load Coupling

This article presents a microstrip bandpass filter (BPF) for wireless LAN applications. The BPF offers a wide upper stopband by using two novel slow-wave resonators. Two transmission zeros are generated on both sides of the passband as a result of sour...
With the rapid development of communication technology, there have been increasing demands for advanced radio frequency (RF) filters with small size, wide stopband and high selectivity. To realize better selectivity, the generation of transmission zeros is very important in the synthesis of modern filters. Most of the research efforts...
