Enhanced Bandwidth of Impulse-Ultra Wideband (I-UWB) Slotted Rectangular Patch Antenna with Partial Ground Plane

An Impulse-Ultra Wideband (I-UWB) slotted rectangular patch antenna with partial ground plane is presented in this paper. The proposed antenna exhibits excellent performance of UWB characteristics with enhanced bandwidth, with impedance bandwidth from 3.34 GHz to 20 GHz, complying with the return loss, S11<-15 dB, and voltage standing wave ratio (VSWR) below 2. The antenna is designed and simulated in CST Microwave Studio. Both simulated and measured results of the antenna design are discussed in detail in this paper.
