A controllable bowtie-like electromagnetic bandgap (EBG)-based microwave filter is proposed in this article. The device exploits EBG properties to form the desired stopband, whereas tunability is used by means of switching elements. Numerical analysis is performed by a finite element scheme revealing the DC-extending bandstop behavior of the structure. In addition, a prototype of the proposed filter is constructed and measured. Experimental data demonstrate the robustness of the conducted simulations, while an adequate tuning range is observed. The simple, yet efficient and easily fabricated, design promises operational reconfigurability combined with amplitude tunability.

In this paper, a compact coplanar waveguide (CPW) resonant cell is introduced, which can exhibit dual-bandgap characteristics by only single unit. The same pattern has been adopted in the microstrip line as reported previously and here is applied to CPW. Experimental results show good agreement with numerical results. By alternating the relative position between CPW defected ground structure (DGS) and split-ring resonator (SRR), the separation between the two resonant frequencies can be controlled easily.

“…Many researchers have proposed several patterns such as Helix PBG [12], circular and annular-ring-patterned PBG [13], and butterfly-radial-slot PBG [14] additionally with multiperiodic or different frequencies structures [15,16] or tapered ones [17,18] presenting stopband characteristics of microstrip lines using finitedifference time-domain (FDTD) simulation and measurement [19] with filtering characteristics.…”

be tuned from 1.06 to 1.42 GHz by using an added varactor diode. Because the SO signals with a 500-MHz external signal having a 0-dBm power level are mixed, the VCO can generate various LO signals. The implemented VCO operates at 3 V with 30-mA current consumption. The output frequencies of the VCO are 787, 1715, and 1900 MHz and these frequencies are dependent upon the capacitance of the varactor diode. The phase noise performance of the VCO is less than Ϫ91 dBc/Hz at 100-kHz offset point and the measured output levels range from Ϫ5.6 to 0 dBm.Although the resonator has a narrow-frequency tuning range, the tuning range of the VCO is expanded from 29% to 109.7%. Since the VCO can generate a number of output signals with various frequency components, it can be used for a complex multiband mobile environment.
