RCS analysis on ultra-wideband sinuous antenna with elliptical slots

Investigation on ultra-wide band slot-sinuous antenna for in band mono static radar cross section behaviour are performed. The possibility of using opening ellipses on the metallic patch of the slot-sinuous antenna are presented with the intent of reducing structural radar cross section on the overall frequency band. Simulated results for in-band RCS for modified slot-sinuous antenna and slot-sinuous are presented discussed. The proposed solution result as a good candidate to be further investigated on a multi-objective optimization context for in band RCS reduction.
