Abstract

This paper presents a compact triple mode band
pass filter (BPF) using dielectric-loaded cylindrical cavity that
allows the realization of three transmission zeros. This class of
triple mode resonator utilizes the dual degenerate TE11 modes
and the single TM01 mode. Coupling structure is based on
choosing the proper resonator height and input/output feeding
probe position (angle Ø) to achieve the desired perturbation
between the degenerate modes. Therefore, no additional space
nor coupling screws is needed. A three-pole BPF is designed to
verify this approach at 2.08 GHz centre frequency with
bandwidth of 42 MHz at -20 dB return loss. The introduced
triple mode resonator can be used as a building block in the
design of diplexers and sophisticated higher order filters.
