One of the methods to achieve multi-band response with compact size and high performance is to employ the stepped impedance resonators (SIRs) [8-10].
Stepped impedance resonators (SIRs) are transmission line resonators utilizing quasi-TEM modes.
A stepped impedance resonator filter is simulated with different DGS geometries to assess the suitability of a given shape for the best return loss performance.

1 introduces the theoretical analysis of the design by using stepped impedance resonator.
Huang "Compact UWB bandpass filter with triple-notched bands using triple-mode stepped impedance resonator," IEEE Microwave and Wireless Components Letters, Vol.
In response to this need, a compact cross-coupled filter using improved SRR based on stepped impedance resonator was proposed, and the improved SRR unit cell only has size of 0.
Yin, "A novel microstrip filter using three-mode stepped impedance resonator (TSIR)," IEEE Microw.
In [16], the dual notches are implemented using open stub, and the UWB BPF is realized using modified distributed highpass filter and slots on the ground plane in the shape of stepped impedance resonator (SIR).
By using the stepped impedance resonator (SIR) and a good impedance matching at input port for two BPFs, a high isolation between two passbands is obtained in [15,16].
These asymmetric tapped feeding lines were also used with a stepped impedance resonator in a bandpass filter [6-9].
In this improved structure, stepped impedance resonator (SIR) [28-31] is used in stead of uniform half-wavelength resonator which can provide additional characteristic admittance [Y.
