Abstract New microstrip slow‐wave bandpass filters using open‐loop resonator loaded with inter‐digital capacitive fingers is proposed. The filter features not only compact in size, but also exhibits spurious stop‐band rejection. Filters of this type with elliptic function and Chebyshev response are demonstrated. There is good agreement between experimental and full‐wave electromagnetic (EM) simulation results. © 2002 Wiley Periodicals, Inc.
