A loxodromic antenna array is a spiral array on the spherical surface. Distribution of elementary antennas on the spherical surface was made by following loxodromic curves. This type of antenna array offers a wide range of opportunities in the variation of their radiation patterns through antenna distribution and phase control. The paper studies different loxodromic antenna arrays based on the influence of an Archimedean spiral configuration pattern on the radiation pattern of a spherical antenna array. Analysis was made using a developed moment method program with a spectral-domain approach.
