  1. 1. Baluns, Hybrids and Power Dividers for Ultra- Wideband Antennas

    Författare :Syed Hasan Raza Zaidi; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multiport feeding network; baluns; packaging; power divider; Ultra-wideband; Eleven feed; gap waveguide; ring hybrid.;

    Sammanfattning : UWB (ultra wideband), depending on the application requirement, is usually referred to 2:1 bandwidth for radio/wireless applications. Here in this thesis it is also used to denote extremely wideband antenna and components at several octave bandwidth, particularly for high frequency applications, such as the 1 – 10 GHz antenna system needed for the Square Kilometer Array (SKA) radio telescope and the 2 – 14 GHz antenna system for the VLBI2010 (Very Long Base line Interferometer) project.
