“…However, these errors can be ignored for the present applications of the slotted ground structures [1-10, 13, 14, 18-20] where their wide stopband and passband are exploited for harmonic suppression and their phase properties as phase sifters. These issues have been addressed in a number of our published works [8,9,13,14]. The discrepancy can also be attributed to the idealness of the calculation blocks and also the fabrication error in the milling machine.…”

Five novel slotted ground microstrip structures have been studied to prove that the gap and the cross junction capacitances and the associated inductance have significant influence on the attenuation poles and passband characteristics. A quasi-static analytical approach based on the concentration of the surface current on the slotted ground plane structure is adopted. Theory is validated against simulation results by commercial Electromagnetic (EM) solver CST Microwave Design Studio TM and measurement by an Agilent performance network analyzer (PNA) E8361A. Robust agreements between theoretical, simulation, and calculated results support the hypothesis. It has been proved that though both the gap and junction capacitances play significant role in determining the attenuation pole, the gap capacitance favorably reduce the location of the attenuation pole with moderately high selectivity of the stopband.

“…Electromagnetic Bandgap (EBG) structures have considerable effects on suppression of the SSN. The coplanar EBG structures possess good performance in low frequency [2][3][4][5][6][7][8][9][10], but the narrow bandwidth makes it cannot achieve the wideband SSN suppression due to the limitations of its own electrical characteristics. The mushroom EBG structure has been embedded between power and ground planes to mitigate the SSN [11][12][13][14], which increases the bandwidth of the stopband, but it decreases low frequency inhibition performance and increases fabrication cost.…”

In this article, by analyzing the equivalent circuit mode for electromagnetic bandgap (EBG), a novel compact planar EBG structure is proposed for overcoming the drawback of narrow bandwidth of conventional EBG structures. The novel design is based on using meander lines to increase the effective inductance of EBG patches. The simulated and measured results demonstrate the simultaneous switching noise (SSN) can be mitigated with an ultra‐wideband from 280 MHz to 20 GHz at the restraining depth of −40 dB. Compared with the traditional L‐bridge and meander lines EBG structures, this novel structure has the advantages of suppression bandwidth and fabrication cost. Moreover, signal integrity is achieved by the time‐domain simulation. The proposed structure provides a new kind of theoretical designing reference for EBG structure to improve the bandwidth of restraining SSN. © 2013 Wiley Periodicals, Inc.

“…These novel and fruitful concepts have given rise to new design approaches that allow us to obtain improved microwave components for upcoming applications. An important research effort was devoted to make these novel periodic structures compatible with planar microwave technologies facilitating their practical implementation and widening significantly the scope of potential usage [6–8]. Specifically, periodic structures of the EBG‐type have been reported as very useful to improve the behavior of planar circuits and antennas by introducing stopbands that forbid the propagation of electromagnetic waves in the unwanted frequency bands and directions.…”

In this article, an analytical solution is obtained for the design of electromagnetic bandgap (EBG) structures that feature a single stopband without the spurious rejected bands present in the conventional EBG devices at the harmonics of the design frequency.The proposed technique is applied for the design of microwave filters intended for broadband applications, where closed formulas are found both in two‐port lines and in four‐port coupled lines obtaining very good results. The implementation of the EBG structure in coupled lines allows for the redirection of the reflected signal to the coupled port producing a device with input port matched at all frequencies. © 2012 Wiley Periodicals, Inc.
