    • Fully integrated LNA & antenna for ultra-low noise figure receivers 

      Krüger, Paulus; Visser, Barend; Prinsloo, David (IEEE, 2017)
      A simple, inexpensive, fully integrated low-noise amplifier and antenna for the Square Kilometer Array (SKA) Mid-Frequency Aperture Array (MFAA) is presented which achieves a receiver noise figure of about 0.4 dB over more ...

    • Noise matching in coupled antennas 

      Krüger, Paulus; Visser, Barend (IEEE, 2018)
      A novel way to calculate the sensitivity and beam- former coefficients of a receiver consisting of coupled antennas and an optimum beamformer is presented. The low-noise ampli- fier (LNA) connected ...

    • Spectral modelling of a H.E.S.S.-detected pulsar wind nebula 

      Van Rensburg, Carlo; Krüger, Paulus; Venter, Christo (SAIP, 2015)
      In the last decade ground-based Imaging Atmospheric Cherenkov Telescopes have discovered roughly 30 pulsar wind nebulae at energies above 100 GeV. We present first results from a leptonic emission code that models the ...
