Planar antennas with enhanced bandwidth and radiation characteristics by Alibakhshikenari, Mohammad, Naser-Moghadasi, Mohammad, Sadeghzadeh, Ramazan Ali, Virdee, Bal Singh, Limiti, Ernesto

“…In this chapter, novel wideband and ultra-wideband (UWB) antennas that are based on loading the background plane of a monopole radiator with concentric split-ring resonators are presented. It is shown that this modification improves the fractional bandwidth of the antenna from 41 to 87%; in particular, the operational bandwidth of the proposed antennas is double that of a conventional monopole antenna of the same size.…”
