“…This has led to new applications in passive devices for guiding and confinement of electromagnetic radiation. Their use in both microwave and optical devices has primarily been limited to passive devices such as waveguides and filters [4], [5], though some applications in active devices have been reported [6]. The results of investigation of the potential of PBG structures for accelerator cavities are also very promising…”

“…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].…”

“…It is much easier to establish the equivalent circuit because the transmission, reflection, and suppression characteristics of DGS microstrip line are very clear and definite. Furthermore, DGS has prominent advantages of being applied to microwave circuits such as filters, dividers, couplers, amplifiers, and so on [7,[9][10][11][12][13][14][15][16][17][18][19][20]. Figure 4 shows the microstrip line with SIAD structures proposed recently [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.

“…Photonic bandgap (PBG) structures have been considered as an alternate to solve this problem in microwave and millimeter-wave circuit applications recently [1][2][3][4][5][6][7][8]. (PBG structures are periodic structures which exhibit a bandgap within a certain band of electromagnetic propagation is prohibited [9,10]).…”
