  • Analysis and design of a wide band omnidirectional antenna 
    Jacobs, Ockert Botha; Odendaal, J.W. (Johann Wilhelm); Joubert, Johan (Wiley, 2011-06)
    The analysis and design of an omni-directional antenna that functions over a very broad frequency band is presented. Design guidelines for this antenna have been derived using electromagnetic analysis software. ...
  • Elliptically shaped quad-ridge horn antennas as feed for a reflector 
    Jacobs, Ockert Botha; Odendaal, J.W. (Johann Wilhelm); Joubert, Johan (Institute of Electrical and Electronics Engineers, 2011)
    Quad-ridge horn antennas of various geometries are considered as possible candidates for a wideband reflector antenna feed. It is demonstrated that shaping the sidewalls of the ridge horns significantly improves the ...
  • Quad-ridge horn antenna with elliptically shaped sidewalls 
    Jacobs, Ockert Botha; Odendaal, J.W. (Johann Wilhelm); Joubert, Johan (Institute of Electrical and Electronics Engineers, 2013)
    We present a quad-ridge horn antenna as a feed for a reflector antenna for use in radio astronomy applications. The antenna uses elliptically shaped sidewalls to limit the variation of beamwidth over a wide frequency ...
