Miniaturisation schemes for metallodielectric electromagnetic bandgap structures

IET Microwaves, Antennas & Propagation, 2007
Two miniaturisation schemes for metallodielectric electromagnetic bandgap (MEBG) arrays are presented. Miniaturisation by virtue of the closely coupling technique as well as by employing complex element geometries is demonstrated by means of full-wave simulations and experimental results.
