A Novel Low-Pass Filter With an Embedded Band-Stop Structure for Improved Stop-Band Characteristics

This letter presents a novel design of a microstrip low- pass filter (LPF) with an embedded band-stop structure, which is constructed from a simple two transmission line band-stop filter. The band-stop structure is ingeniously embedded into a classical step-impedance microstrip LPF. The stop-band of...
