摘要：
A novel miniaturized planar monopole antenna for ultra-wideband (UWB) applications with dual band-notched function is proposed in this paper.The proposed antenna consists of an ordinary square radiating patch with a π-shaped slot,a modified W-shaped slit and a pair of L-shaped branches.By adding the pair of L-shaped branches,additional resonances are excited and wider impedance bandwidth can be produced.To generate dual band-notched characteristics,a π-shaped slot in the radiating patch surrounded by a modified W-shaped slit is etched.The antenna provides a wide usable fractional bandwidth of more than 130% (2.77-13.62GHz).In addition,the designed antenna has a small size of 12×18×1.6mm3 while showing the band-rejection performance,covering all the 3.5/5.5-GHz WiMAX,4-GHz C-bands and 5.2/5.8-GHz WLAN.Simulated and measured results show good band-notched functions,stable gain and nearly omnidirectional radiation patterns of the proposed antenna over the entire UWB frequency. © 2016, Chinese Institute of Electronics.
