Abstract :
A bilateral Vivaldi antenna with reduced radar cross-section (RCS) is presented. A half-mode substrate integrated waveguide structure is first utilised in the low RCS Vivaldi antenna design. Compared with traditional antenna, the monostatic RCS of the proposed antenna can be reduced to as much as 24 dB without degradation of antenna performance.
