Abstract
An electromagnetic bandgap structure comprising a progressive cascade of a plurality of patterns of cells. The cells of each pattern are dimensioned so that each pattern has a reflection phase response centered at a different, but closely-spaced, frequency compared with the reflection phase response of an adjacently positioned pattern, so that the combined reflection phase response of the plurality of patterns provides a continuous wideband operational range.
