Analysis and design of wideband flat lens antennas based on artificial dielectrics

Activity: Talk or presentation › Talk or presentation at a conference

Description

This work describes the analysis and design of wideband flat lenses based on artificial dielectric layers. Planar lenses based on metasurfaces or resonant elements are typically narrowband, due to the phase wrapping over the period of 2π that is strongly frequency dependent. On the contrary, true-time-delay (TTD) planar lenses, which do not resort to phase discontinuities, can achieve large bandwidths. Here, artificial dielectric layers are employed to design wideband TTD lenses with low profile and low reflection.
