Frequency transformation technique has been used for designing a six‐pole (3 × 2 pole) symmetrical triple‐band bandpass filter. Coupling matrix is obtained for filter specifications with 20‐dB return loss in the passbands, 500 MHz overall 3‐dB bandwidth, and 3‐GHz center frequency. Square split ring resonator (SRR) has been used for implementing the coupling matrix which provides miniaturization....
This paper presents the design and implementation of acompact dual-band band-pass filter using metamaterial Split Ring Resonators. The coupling matrix is generated by frequency transformation technique applied to advance filtering functions for symmetric dual-band band-pass filter. The dual-band filter (2×2) pole, with return loss20 dB and bandwidth of 142 MHz and 138 MHz in two bands, at center frequencies3...
This paper discusses the coupling coefficients for electric, magnetic and mixed coupling between synchronous Split Ring Resonators (SRR) using HFSS eigen mode solver. Coupling coefficient variation with the spacing between the coupled resonators has been given which can be used to design microwave filters using SRR. The identification of couplings has been done by observing the current densities of...
