The objective of this thesis is to investigate and design smaller and wideband metamaterial-inspired antennas for personal communication applications, especially for WiMAX, lower band and higher band WLAN applications.

The first design to be analysed is a low-profile metamaterial-inspired CPW-Fed monopole antenna for WLAN applications.
