Abstract
At present,a lot of ultra-wideband(UWB) phased arrays have been designed based on the strong mutual coupling between the array elements.But the UWB phased arrays are large.For a small scale or a small scale array in the scanning direction,the problem of how to achieve the ultra-wideband perform-ances by enhancing the mutual coupling between the array elements is necessary to be developed.In this paper,Balanced Antipodal Vivaldi Antennas (BAVAs) are adopted. By optimizing the radiation metal shape and arranging the direction of the antenna elements with mirroring technique,a small 4×16 oblique polarization UWB phased array is designed.The simulation and experiment results show that this method can enhance the mutual coupling between the small UWB array elements. The array has a good voltage standing-wave ratio(VSWR) less than 2.0 in the frequency 0.8f0~2.0f0(f0is the operation frequency), norm gain 17.34 ~23.0 dBi,and large scanning angle beyond 45° without grating lobes. The designed small scale UWB phased array antenna has been applied in engineering.关键词
