A Designed of Miniaturized Vivaldi Antenna for Antenna array applications

  This paper presents a miniaturized Vivaldi antenna in order to meet the practical requirements of antenna array applications.Compared to the conventional Vivaldi antenna(CVA),the width of the modified Vivaldi antenna aperture is reduced 38.05%by adding regular slot edges(RSE),which will prevent the antenna array from generating the grating lobes.Additionally,the RSE has improved the radiative features of antenna.It mitigates the side lobe level,overcomes the beamsquint at E-plane,and increases gain.The parameters of the CVA and CVA-RSE are optimized.The simulated impedance bandwidth(VSWR<2)is approximately from 7.85 GHz to 12 GHz for both of them.A comparison between the modified CVARSE and CVA at 12 GHz shows an improved gain of 10.8 dB,-13.3 dB of the Side Lobe Level(SLL),and 0 degrees of the Main Lobe Squint(MLS)at E-plane,in contrast with 9.5 dB of gain,-9.9 dB of SLL,and 2 degrees of the MLS at E-plane in the conventional Vivaldi antenna.
