Parametric Analysis of Wearable Vialess EBG Structures and Its Alication for Low Profile Antennas
Abstract: Electromagnetic
Bandgap (EBG) structures are one class of metamaterial with attractive properties
that unavailable in nature and widely used for improving the electromagnetic
performance. Its In-phase reflection frequency band is indicated as operation
frequency band, whose characteristic is closely related to the parameters of
EBG structure, such as patch width (w), gap width (g), substrate height (h) and
substrate permittivity (ε). The presence of via within EBG structure is
associated with design and fabrication complexities, which led the researchers
to study uniplanar EBG. These structures require no via and can easily be
fabricated and integrated with RF and microwaves alication. Therefore, an
investigation study on the effect of the parameters of the vialess EBG surface
and some design guidelines have been obtained. An example of an antenna
integrated with EBG is also studied. The result indicates that the EBG ground
plane significantly improves the work efficiency of the antenna in a particular
frequency band.
