The article is devoted to the use of ring and spiral-ring antenna arrays that implement the circuit-spatial addition of incoherent signals when working on diagram-forming circuits that form various options for amplitude-phase distributions.

The radiation characteristics of annular and spiral-annular antenna arrays are calculated for various excitation options.

A comparative analysis of the obtained results was carried out. The degree of improvement in the radiation characteristics in the case of using the spiral-ring antenna arrays as a radiating structure in comparison with the ring antenna arrays is shown.
