Abstract :
A substrate integrated waveguide Vivaldi array antenna is designed and analyzed. The array antenna is made of two Vivaldi structure radiation elements, and the antenna is fed by an equal power divider with substrate integrated waveguide technology. Each radiation element is index gradient antipodal structure are on both sides of substrate. The reflection coefficient of the array antenna is less than -10 dB from 8.6 GHz to 10 GHz. The gain of the array antenna is 10.3dB.
