Treatise of the Running-Wave Antenna (2015)
DE PB NW RPISBN: 9783659711756 bzw. 3659711756, in Deutsch, LAP Lambert Academic Publishing Jun 2015, Taschenbuch, neu, Nachdruck.
Von Händler/Antiquariat, AHA-BUCH GmbH [51283250], Einbeck, Germany.
This item is printed on demand - Print on Demand Titel. Neuware - New calculation of optimal parameters for Uda-Yagi plane antenna with elements parallel to ideally conducting Earth is presented. Antenna consists of cylindrical elements same diameter each, namely reflector, driven element and a number of directors with lengths slightly varying to give the radiation pattern desirable. Calculations are aimed at maximizing forward/back intensity ratio called 'shield coefficient' and/or direct wave intensity. We study the case of four directors, which may be modified with no loss of generality. Simple analytical expressions for current distribution in large and small (in comparison to wavelength) cylindrical antennas were given before .We procreate numerical method ( with explicit accuracy evaluation) for calculation of the Green's function free of restrictions which all of these would entail and implement it to the Uda-Yagi antenna with elements of finite electrical conductivity . Skin depth should be small compared to the diameter of antenna elements. Current distributions in the reflector, driven element and directors, which produce the electric field corresponding to Ohm's Law on their lateral surfaces and turn into zeros at the edges. 56 pp. Englisch.
