Abstract:
The CAD of dual-mode HE11 dielectric resonator (DR)
microwave filters is extended to include time-domain methods. S-parameters
are computed for a four-pole dual-mode HE11 DR filter using the
FDTD over both wide and narrow bandwidths, and are compared with
measured values. The spurious suppression predicted using the FDTD
agrees very well with the measured results, justifying the use of timedomain
CAD methods for dual-mode DR filters.
