In this work, a broadband dual-polarized base station array is designed. The 1400MHz-2700MHz band is covered by a single broadband Vivaldi antenna element. The 690MHz-960MHz band is covered by a conventional dipole-like element. The array synthesis has been carried out by time-domain full-wave simulations where excitation is applied to a unit cell embedded in an array. Then, array theory is applied to estimate the far-field of the entire structure. This is computationally efficient, which allows us to optimize the performance of the array with both analytical and numerical approaches.
