Abstract :
Gradient index lenses are proposed to transform a cylindrical wave into a plane one. The lenses are designed from metamaterials engineering in a wide frequency band. A primary source operating in the whole X-band is used to feed the lenses. The lens-antenna systems are low profile and exhibit a directive emission in the H-plane. A very good agreement is observed between measurements performed on the fabricated lens-antennas and numerical simulations.
