dc.description.abstract | This paper presents a lumped-element equivalent circuit model of microstrip lines loaded
with dumbbell defect-ground-structure (DB-DGS) resonators, etched in the ground plane. The model is
valid for ordinary (i.e., unfolded) DB-DGSs, as well as for folded DB-DGSs with an arbitrary aperture
angle and relative orientation between the line and the resonator. It is shown that in folded, or partially
folded, DB-DGS resonators both magnetic and electric coupling between the line and the resonator should
be considered, except for a particular DB-DGS orientation, namely, the one where the symmetry plane of
the particle (a magnetic wall) is orthogonal to the line axis. In this case, the particle is exclusively excited
by the electric field generated by the line. It is also shown that the circuit model of a microstrip line loaded
with an unfolded DB-DGS resonator transversally oriented to the line can be derived from the general model
by considering the effects of opening the particle, i.e., a reduction of the electric coupling. In the extreme
situation where the DB-DGS is completely opened (unfolded), the electric coupling vanishes, and the particle
is exclusively driven by the magnetic field generated by the line. This effect is taken into account in the model
by considering that the capacitance between the line and the inner metallic region of the folded, or partially
folded, DB-DGS depends on the aperture angle of the particle, and it is null when the particle is unfolded.
The models are validated by parameter extraction and comparison of the circuit responses with the responses
inferred by electromagnetic simulation and measurement. | es |
