    • 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 ...

    • Sensitivity of static energy meter reading errors to changes in non-sinusoidal load conditions 

      Marais, Z.; Rens, J.; Van den Brom, H.E.; Rietveld, G.; Van Leeuwen, R. (IEEE, 2019)
      Previous studies regarding static energy meter errors under non-sinusoidal load conditions have shown that these meters can produce erroneous readings. This paper describes an investigation done using loads consisting ...
