Design of A Broadband Vertically Polarized Omnidirectional Array Based on Vivaldi Antenna
Using eight Vivaldi elements,a wideband omnidirectional array is proposed in this paper.First,in order to achieve roundness radiation pattern of array in horizontal plane,a Fermi Vivaldi antenna is optimized,which can achieve a 3-dB beam width of 45°(±10°)from 5.5GHz to 7.6GHz.Then,the elements in the H-plane with periodic angle of 45° are employed to build the circular array.Finally,the array is fabricated and its performance is evaluated.Measured result shows the designed array can obtain a bandwidth from 5.5 to 7.6GHz for both omnidirectional radiation pattern and S11≤-10 dB.In addition,this array has a potential application for beam switching with smooth angular variation over a 360° range.
