摘要：
In this paper, we propose a 3D tapered aperture design, a.k.a the 3D Vivaldi, that yields dual-polarization with high cross-polarization isolation over a 20:1 bandwidth. We also discuss utilizing the 3D Vivaldi in an ultra-wideband array covering 2-40 GHz. To avoid grating lobes in the array, we explore the use of particle swarm optimization, a bio-inspired optimization technique, to create aperiodic spacings between the 3D Vivaldi elements in order to help suppress grating lobes up to 10 dB from 2-40 GHz.
