Abstract In this letter, a novel microstrip bandpass filter (BPF) with half asymmetric resonators is presented.With Filter structure and capacitively loaded coupling, a wide bandwidth with sufficient rejection level can be achieved easily. The electromagnetic simulation is used, and the prototype of the BPF is fabricated and measured. Comparisons of simulated results and experimental data are shown; moreover, good match validates the proposed filter. © 2010 Wiley Periodicals, Inc.
