The polymer-based resonator used in RIOG requires a much larger diameter and a lower propagation loss because the performance of gyroscope mainly depends on the enclosed area and the propagation loss of the waveguide resonator

To verify the fact that the proposed coupling structure can be used as the negative coupling structure for the substrate-integrated waveguide resonator
, we designed an elliptic-response filter that requires the negative coupling structure.
In the approach direct-coupled waveguide resonator
filters are designed by starting from a prototype with inverter-coupled lumped -element resonators.
[xi] = [[lambda].sub.10r]/[[lambda].sub.10] - [[lambda].sub.10]/[[lambda].sub.10r] is a waveguide resonator
variable expressed in terms of wavelength
As is known to us that although the filter based on half-wave coplanar waveguide resonator
is widely used, there are spurious responses around n[f.sub.0]  ([f.sub.0] is the center frequency of the passband).
Since the rectangular [TE.sub.101] waveguide resonator
is folded along the thickness direction twice, there is about 50% reduction in the overall volume if the thickness of two dielectric layers is taken into consideration.

This device also was tested in a waveguide resonator
and provided a maximum output power of 15 mW.
Next the Qs are weighted with [Q.sub.T] and [Delta] that is a correction factor to correlate a lumped-element resonator to an evanescent mode waveguide resonator
