A new compact leaf shaped CPW fed UWB antenna

Abstract

A new leaf shaped compact (40mm×30mm×0.8mm) CPW fed UWB antenna is proposed. The proposed antenna gives an impedance bandwidth improvement of more than 134% with nearly omnidirectional H-plane pattern and monopole like E- plane pattern. The antenna also provide sufficient average radiation efficiency of more than 87%, flat gain variation of 2.5— 5.5 dBi, linear transfer function and minimal group delay variation. A good matching between simulated and measured results are observed.
