Abstract :
The development of a dielectric grating antenna at Ka band is presented. The antenna performance is analyzed using perturbation analysis and a numerically based commercial software. The effect of the grating profile and various dimensions on the performance is presented. Based on the analytical results a rectangular profile grating antenna is designed. The antenna is optimized, fabricated and measured. Close agreement between the simulated and measured results is obtained.
