“…There is an increasing trend of multifunctional and frequencyagile wireless systems to achieve high integrity, miniaturization, multifunction and flexibility [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. In developing such systems, dualand triple-band bandstop filters are essential components, which can suppress the unwanted concurrent signals at separate frequencies [7][8][9][10][11][12][13][14][15].…”

Abstract-A novel design of planar dual and triple narrow-band bandstop filter is presented by adopting the proposed meandered slot defected microstrip structure (MS-DMS) and the simplified spiral microstrip resonator (SSMR). Through this design, the stopbands of the dual-and triple-band bandstop filters can be individually controlled and the improved spurious responses are achieved. First, the fundamental and the first spurious resonances of the MS-DMS and SSMR are analyzed to provide the design rules. Then, by utilizing the prominent stopband of the MS-DMS and the stopband produced by the SSMR coupled to main microstrip line, a dual narrowband bandstop filter is constructed before its design procedure is outlined. Based on above investigations, a triple narrow-band bandstop filter is implemented by inserting extra SSMRs to another side of the main microstrip line of the dual-band filter to generate a new stopband. To verify the aforementioned design concepts, a dual and triple narrow-band bandstop filter are designed, simulated and tested. Both the simulation and measurement indicate that the fabricated filters exhibit good stopband/passband performance and improved first spurious resonance. Moreover, these filters are simple to design and quite compatible with planar fabrication technique, making them very attractive for practical applications.

“…Multi-band bandstop filters play an important role and are tremendously preferred, which can be simultaneously used for stopping different signal frequencies. Some effective methods have been proposed to develop dual-band [1][2][3][4] and triple-band bandstop filters [5][6][7][8][9][10][11][12]. However, the design of triple-band bandstop filters (TB-BSFs) and controlling the stopband frequencies within the specified band are difficult.…”

Abstract-This paper presents a design of compact a triple-band bandstop filter (BSF) using embedded chip capacitors. The presented BSF is useful to suppressing the signal frequencies 2.2 GHz, 5.53 GHz and 4.15 GHz from the WLAN and UWB band with attenuation level 33.5 dB, 27.6 dB and 24.9 dB, respectively. The quality factors of the three bands are 5.21, 31.92 and 79.0, respectively. The simulated and measured results are presented to validate the concept. Such BSFs could find application in modern communication systems to suppress the potential interference of the unwanted frequencies from the WLAN and UWB band.

Abstract-In this paper, the potential use of split ring resonators (SRRs) to design very compact dual-band bandstop waveguide filters is proposed. Two square SRRs are placed on the same transverse plane realizing two independent reject bands. By adjusting the SRRs lengths, the stopbands can be targeted at the desired frequencies. In addition, a simple circuit model for this resonator is introduced. Good agreement between the experimental and full-wave simulated results has been achieved.
