Description
  • A suitable way of characterizing antennas in a wide band of frequencies is investigated. First, a canonical antenna is characterized by conventional parameters in the frequency domain (directivity pattern, gain, input impedance) on each separate harmonics, and their mean value counterparts are formulated and discussed. Second, the analysis is performed in the time domain, and following the frequency domain characterization, time-domain parameters are formulated. The correspondence between frequency-domaain parameters and time-domain ones is shown using Parseval's theorem. Third, sources of analysis inaccuracies in both the domains are discussed, and ways of suppressing them directly in the domain of analysis are proposed.

  • Je zkoumán vhodný způsob charakterizace antén v širokém pásmu kmitočtů. Jako kanonická struktura je charakterizován drátový dipól - nejprve konvenčním způsobem v kmitočtové oblasti (směrový diagram, zisk, vstupní impedance) na jednotlivých harmonických, a poté pomocí středních hodnot těchto veličin. Následně je analýza přenesena do časové oblasti a jsou formulovány parametry časové domény. Souvislot mezi oběma typy parametrů je ověřena aplikací Parcevalova teorému. Konečně jsou diskutovány zdroje nepřessností v obou oblastech a jsou navrženy postupy jejich přímé korekce. (cs)
