Capacitively loaded coplanar waveguide (CPW) open-loop resonators (OLRs) are proposed for maximum miniaturization in uniplanar microwave applications. It is shown that these resonators can be used to achieve a slow-wave ...

Novel slow-wave CPW resonators with defected ground structures (DGSs) in a rectangularly spaced and open-loop shapes are investigated. These structures have an extremely compact size. The simulations and experimental results ...

A compact, low-loss and narrowband dual-mode microstrip filter is proposed using degenerate modes of a microstrip patch resonator loaded with two narrow slots. The resonator structure is fed by inset lines connected directly ...
