A novel realisation of quasielliptic function narrowband bandpass filters constructed from face-to-face dual-mode microstrip square loop resonators is proposed. The new filter configuration allows crosscoupling between the degenerate modes of individual dual-mode resonators. The realisation has been confirmed both theoretically and experimentally.
