“…Dual-band bandpass filters have gained great attention in wireless communication systems recently [5][6][7][8][9][10]. The initial type of dualband filter is simply designed by connecting two filter circuits with two different passbands [5].…”

Abstract-A compact dual-band bandpass filter using equal-length split-ring resonators (SRRs) is proposed in this paper. The tworesonance frequency response of equal-length split-ring resonator is described in detail. A cross-coupled dual-band filter with four equallength split-ring resonators is designed. Several finite out-of-band attenuation poles are realized to improve the selectivity of the proposed filter. The measurement of the filter is in good agreement with the simulation.

“…Open loops are used to reduce the antenna size (thanks to their reduced footprint), achieved due to the fundamental resonance occurring at frequencies much lower than that of only one open-loop resonator with the same dimensions (subwavelength effect) [16]. When the surface of the SRR is exposed to a perpendicular magnetic field, currents are induced in the rings, and they are able to pass from one ring to another [17].…”

Abstract-An omnidirectional compact antenna based on dual-band Split Ring Resonators (SRRs) for 2.45 GHz wireless local area network (WLAN) and 3.5 GHz worldwide interoperability for microwave access (WiMAX) applications is presented. Different and new properties of SRRs, such as dual-band or multi-band performance in the design of compact antennas, can be obtained by making the rings unequal and asymmetric. The dual-band SRR antenna is designed with a bandwidth control technique based on the stored electromagnetic energy in the resonator rings. The obtained results show that the SRR antenna has good omnidirectional radiation pattern for both bands and good impedance bandwidth. In addition, compactness and flexibility are obtained with a simple structure of the SRRs.

“…The basic ring resonator consists of two feeding lines that are coupled to a ring, whose electrical length is a multiple of the wavelength at the desired resonance frequency. Additionally, some modifications may be introduced in this structure in order to obtain a dual-band response in different passive configurations [19][20][21][22][23][24][25]. On the other hand, active components can be added in the ring in order to compensate the losses introduced by the transmission lines [26].…”

Abstract-In this paper, a novel dual-band active filter topology is presented. The non-linear phase response of a composite right/lefthanded cell is used to achieve the desired dual-band performance. Additionally, the proposed structure based on coupled ring resonators yields a very compact solution in which high-order implementations can be easily obtained by cascading multiple rings. The theoretical principles of this type of filters are analyzed in detail. Finally, three prototypes based on first-, second-and third-order structures validate the feasibility of this type of filters. Good agreement between simulations and measurements has been achieved.
