In this structure gaps and metallic patch dimensions have an effect on electromagnetic band gap is observed. It is shown that elliptic mushrooms can show much better performance compared to its conventional counterpart such as perfectly electric conductor. Good return loss in the EBG frequency range for HIGP-low profile dipole antenna is obtained. Miniaturized and improved antenna system is satisfied by this new elliptic mushrooms.eninfo:eu-repo/semantics/closedAccessHigh impedance ground planeElectromagnetic band gapMetamaterialArticle41118981900WOS:000285399400067Q4
