Presented here is a reactively loaded microstrip transmission line that exhibit an ultra-wide
bandgap. The reactive loading is periodically distributed along the transmission line, which is
electromagnetically coupled. The reactive load consists of a circular shaped patch which is converted
to a metamaterial structure by embedded on it two concentric slit-rings. The patch is connected to
the ground plane with a via-hole. The resulting structure exhibits electromagnetic bandgap (EBG)
properties. The size and gap between the slit-rings dictate the magnitude of the reactive loading.
The structure was frst theoretically modelled to gain insight of the characterizing parameters. The
equivalent circuit was verifed using a full-wave 3D electromagnetic (EM) solver. The measured results
show the proposed EBG structure has a highly sharp 3-dB skirt and a very wide bandgap, which is
substantially larger than any EBG structure reported to date. The bandgap rejection of the single
EBG unit-cell is better than − 30 dB, and the fve element EBG unit-cell is better than − 90 dB. The
innovation can be used in various applications such as biomedical applications that are requiring sharp
roll-of rates and high stopband rejection thus enabling efcient use of the EM spectrum. This can
reduce guard band and thereby increase the channel capacity of wireless systems. [--]
