A planar UWB antenna with quad notched bands using rake-shaped resonator and L-shaped slots

摘要

A planar ultra-wideband (UWB) antenna with quad notched bands is proposed and its performance is investigated in this paper. The designed UWB antenna consists of a rectangle-shaped radiating patch with tapers and a polygon ground plane with a rectangular slot. A rake-shaped resonator (RSR) and a pair of L-shaped slots (LSSs) are employed to achieve the desired four notched bands which are operated at 3.3-3.6GHz for WiMAX, 3.9-4.0GHz for C-band, 5.6-5.9GHz for WLAN and 7.9-8.2GHz for ITU 8 GHz band. The results show that the proposed antenna has very wide bandwidth ranging from 2.7 to 12.0 GHz with respect to VSWR 收起
