ABSTRACT
This paper presents the design of a Vivaldi antenna loaded with trapezoidal and arc grooves for reducing radar detection of special stealth equipment monitoring. By investigating the surface currents of the Vivaldi antenna in both scattering and radiating aspects, the modification of the antenna's shape and radiating performance is determined. The trapezoidal and arc grooves are incorporated into the antenna design to minimize the radar cross section (RCS) while maintaining almost unchanged radiating performance. The operating frequency of the antenna is 16.4 GHz to 26 GHz, with a maximum RCS reduction of 10.6 dB in the frequency band. The gain reaches 10 dB. To further enhance the antenna's performance, a curved slot is loaded on top of the Vivaldi antenna. Compared to the Vivaldi antenna loaded with trapezoidal slots only, the curved slots result in a maximum RCS reduction of 6.2 dB in the low frequency band (16.4 GHz to 21 GHz). This improvement has no impact on the operating band from 16.4 GHz to 26 GHz and virtually no effect on the radiating performance. The proposed Vivaldi antenna loaded with trapezoidal and arc grooves demonstrates an effective approach for reducing radar detection of special stealth equipment monitoring while maintaining superior performance. This research provides valuable insights into the design of stealth antennas for enhanced RCS reduction and improved radiating performance.
