Abstract
The use of an array of miniaturized elliptical substrate lenses or mini-lenses, combined with an array of printed antennas, is proposed for plasma imaging applications. Compared with its predecessor, the large hyper hemispherical lens, the new configuration demonstrates reduced sidelobe levels, minimal off-axis aberrations, increased RF bandwidth, and enhanced local oscillator coupling with substrate side LO illumination.
