Material-loaded high q-factor slot resonator and measurement of relative permittivity
Abstract
<p>We introduce a new slot resonator in the ground plane of a microstrip that is loaded with a parallel plate capacitor. The loaded slot has a 73% reduced length. Its unloaded Q-factor is 98 which is 91% higher than that of an ordinary slot. It is suitable to reject the narrow band unwanted signal. The proposed high Q-factor compact slot resonator also suppresses the undesired spurious high frequency response of the unloaded slot resonator. The structure is further used to determine the unknown dielectric constant of a sheet material with 0.04 variation in ε<sub>r</sub>.</p>
