This paper introduces a real-time multiple input and multiple output (MIMO) channel sounder to measure the vehicle-to-vehicle (V2V) propagation channel at 5.9 GHz. Compared to the existing V2V channel sounders, our design emphasizes on improving the stability of the setup and increasing the MIMO snapshot rate. The system stability allows us to develop a high resolution parameter extraction algorithm...
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...
