Fractal Fresnel lens

Farahan Abdul Ghaffar, et al., "24-GHz LTCC Fractal Antenna Array SoP With Integrated Fresnel Lens" IEEE Antennas and Wireless Propagation Letters, 10, 2011, 705. Abstract: A novel 24-GHz mixed low-temperature co-fired ceramic (LTCC) tape based system-on-package (SoP) is presented, which incorporates a fractal antenna array with an integrated grooved Fresnel lens. The four-element fractal array employs a relatively low dielectric constant substrate (CT707, ), whereas the lens has been realized on a high-dielectric-constant superstrate (CT765, ). The two (substrate and super- strate) are
