Abstract :
In this paper, the NRI lens antenna using dielectric resonators for wide angle beam scanning is presented. The constant beam scanning characteristics of the NRI lens antenna is confirmed. And the reduction of the antenna efficiency is due to the dielectric loss of the parallel plate waveguide and the staircase approximation of the lens shape.
