New Design Antenna and Optimization of S‐Band Radar Networks Using CSRR Technology

International Journal of RF and Microwave Computer-Aided Engineering, Volume 2026, Issue 1, 2026.
In this paper, a new design and analysis of a highly compact metamaterial antenna array for radar applications operating in the S‐band (2–4 GHz) is presented. To enhance the electrical and radiation characteristics of the proposed antenna, a slot was introduced into the radiating element, and a novel power divider was employed.
