Analysis and design of a novel dielectric grating antenna at millimeter wave frequency

The development of a dielectric grating antenna at K/sub a/-band is presented. The antenna performance is analyzed using perturbation analysis and numerically based commercial software. The effect of the 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.
