Abstract

Currently, spiral antennas are widely studied and applied for both military and civilian purposes. However, ensuring that the antenna system operates effectively across a wide frequency range while still meeting gain and directionality requirements is a complex problem. In this article, the authors present the results of research and design of spiral antennas operating in the 2 to 4 GHz frequency range (S band). The analysis of operating principles, calculations, and simulations using CST 2019 software demonstrates that the antenna system operates over a broad frequency range, meeting the requirements of passive radar stations.
