“…A popular PBG structure for microwave application is realized by etching the ground metal plane or constructing the dielectric-holes around the signal line infinitely and periodically [3,17]. Figure 2 shows the representative PBG structure for planar microstrip line proposed by Radisic et al [3,17].…”

“…Recently, microstrip transmission lines combined by perturbation or modified ground structures (MGS) such as defected ground structure (DGS), photonic bandgap (PBG), and substrate integrated artificial dielectric (SIAD) structures have been proposed and studied popularly [2][3][4][5][6]. In addition, those structures have been widely applied to high frequency circuits such as filters, dividers, couplers, mixers, amplifiers, multipliers, baluns, and antennas [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25].…”

“…It is well known that modified transmission lines (MTL) -transmission lines with a perturbation such as periodicity or modified dielectric and ground structures -have some modification in the electrical length, slow wave factor (SWF), characteristic impedance (Z c ), and effective dielectric constant from the typical values [2][3][4][5][6].…”

Abstract-In this paper, a new calculating method for the characteristic impedance (Z c ) of transmission lines with perturbation and periodic modified ground structure (MGS), such as defected ground structure (DGS), photonic bandgap (PBG), and substrate integrated artificial dielectric (SIAD), is discussed. The proposed method is based on simple transmission line theories and proper related equations. The previous method to find Z c of transmission lines with MGS or perturbation produces the fluctuating Z c value depending on frequency, while the proposed method results in a constant value without frequency-dependence. As examples, several microstrip lines with DGS, PBG, and SIAD structure are simulated and measured, and their Z c values are calculated from S-parameters by the previous and proposed methods. It is shown that the Z c obtained by the proposed method is much more reliable than that calculated by the previous method for all examples.

Abstract-A new slotted ground structure featuring compact size and spurious-free passband in the context of microstrip lines is proposed. The compactness of the new structure originates from the lengthened coupling gap in the ground. The spurious-free response in a wide passband is a result of combining both narrow and wide slots in the new structure, which effectively forms a stepped-impedance slot resonator. Compared to the previously proposed dumbbell-and H-shaped defected ground structure, over 40% size reduction can be realized in the new structure. The new structure also provides flexibilities in introducing additional functionalities to the bandstop resonators. By embedding varactors in the slotted ground structure, tunable bandstop resonators can be implemented and 13% tuning range centered at 2.36 or 2.67 GHz have been obtained. Index Terms-Defected ground structure, microstrip, slotted ground structure, tunable bandstop resonator.

By using tapering techniques in recently proposed two‐dimensional (2‐D) photonic bandgap (PBG) structures for microstrip lines, a great improvement in the sidelobe level of the frequency response is achieved. Simulations have been performed by using HPTM Momentum and, in accordance with the measurements, give promising potential for these structures. ©1999 John Wiley & Sons, Inc.
