      Aliakbarian, Hadi; Van der Westhuizen, Ewald; Wiid, Riaan; Volskiy, Vladimir; Wolhuter, Riaan; Vandenbosch, Guy A. E. (Radioengineering Society, 2014)
      Deployment of a satellite borne, steerable antenna array with higher directivity and gain in Low Earth Orbit makes sense to reduce ground station complexity and cost, while still maintaining a reasonable link budget. The ...
    • Kompakte lae-verlies diplekser met gestapte transmissielyn resoneerder 

      Anthonissen, Lukas Willem (Stellenbosch : Stellenbosch University, 1993)
      ENGLISH ABSTRACT: The design of a compact narrowband UHF diplexer involves a complicated network synthesis problem. The complexity of the synthesis problem, in particular the diplexing of two signal paths to achieve a three ...
    • Machine learning approach to radio frequency interference(RFI) classification in Radio Astronomy 

      Wolfaardt, Cornelis Johannes (Stellenbosch : Stellenbosch University, 2016-03)
      ENGLISH ABSTRACT: Radio frequency interference (RFI) presents a large problem for radio telescopes. Interference prevents observations from being made, or extends the duration required for observations. This thesis ...
