A reconfigurable electromagnetic band gap (REBG) structure board is analyzed and designed in this paper. It is composed of a mushroom type EBG board, varactor diodes array, chip inductors and a digitally programmable DC controlling circuit. By changing the bias voltage on the varactor diodes, the surface-wave suppressive band gap of the EBG board can be tuned from 1.86 GHz to 6.32 GHz. Furthermore,...
Two novel wavy electromagnetic bandgap (EBG) structures have been proposed and applied to power/ground plane pairs for ultra-wideband ground bounce noise (GBN) suppression. The proposed two designs have shown good performance. The -40 dB suppression bandwidth of the first design is from 344 MHz to 20 GHz. For the second design, the -49 dB suppression bandwidth is from 304 MHz to 20 GHz. Both results...
In this paper, a type of thin planar absorbing structure of Jerusalem cross slot (JCS) is presented, which has the virtue of wider bandwidth and broader adjustment range. The absorption frequency band can be flexibly adjusted by the slot parameters. The influences of various structure parameters of JCS, incident wave polarization and variation of incident angles on the absorption characteristics are...
In this paper, a novel uniplanar compact EBG structure which integrates L-bridged EBG structure with slits is proposed for ultra-wideband GBN suppression in PCBs. The GBN suppression bandwidth is broadened to cover from 432 MHz to 15 GHz without using multilayer and cascading different period structures. The distinctive behavior of the new EBG power plane in ultra-wideband suppression of the GBN is...
In this paper, we report our experimental and numerical results, confirming the phenomenon of dual in-phase reflection, i.e. dual-resonant behavior, for a TM-polarization plane wave oblique incidence on the conventional mushroom-like EBG structures. A modified local resonance cavity (MLRCC) model of EBG structures has been presented to explain the essential features of dual- resonant behavior and...
