Triple-band microstrip Wilkinson power dividers with controllable frequency responses

The design methodology and implementation of two novel triple-band Wilkinson power dividers is presented. Based on the bandpass filter design with the compensation technique to improve the matching property within each passband region, two triple-band Wilkinson power dividers with Chebyshev response are realized by microstrip open and short stubs and patterned-ground-structure stubs, and are validated by the equivalent-circuit model, full-wave simulation, and measurement.
