“…9 According to the radiation principle, the lowest frequency of Vivaldi antenna is determined by the maximum width of the taper slot. 10 So the lower the operating frequency, the larger the antenna size, which is not conducive to the miniaturization requirements of modern antennas.…”

“…The planar Vivaldi antenna is widely applied in UWB systems due to its advantages such as good directionality and low cross polarization 9 . According to the radiation principle, the lowest frequency of Vivaldi antenna is determined by the maximum width of the taper slot 10 . So the lower the operating frequency, the larger the antenna size, which is not conducive to the miniaturization requirements of modern antennas.…”

“…High performance UWB antenna plays a very important role in UWB communication system 7 . The UWB antennas are mainly divided into dielectric resonator antennas (DRA) 8 , 9 , slot antenna 10 , 11 , Vivaldi antenna 12 , 13 , monopole antenna 14 , 15 and other microstrip patch antenna 16 18 , etc. Among these design methods, monopole microstrip antennas have gradually obtained the widespread attentions due to unique characteristics of compact size, light weight, low profile, low cost, easy fabrication and conformal nature 19 .…”

“…High performance UWB antenna plays a very important role in UWB communication system 7 . The UWB antennas are mainly divided into dielectric resonator antennas (DRA) 8,9 , slot antenna 10,11 , Vivaldi antenna 12,13 , monopole antenna 14,15 and other microstrip patch antenna [16][17][18] , etc. Among these design methods, monopole microstrip antennas have gradually obtained the widespread attentions due to unique characteristics of compact size, light weight, low profile, low cost, easy fabrication and conformal nature 19 .However, although UWB antennas have a highly reliable quality, several narrow frequency bands can interfere with the UWB performance since it can inevitably affect the transmission spectrum, reliability and quality, such as WiMAX band (3.3-3.7 GHz), WLAN frequency band (5.15-5.825 GHz).…”
