Abstract
Elektromagnetska energija prenosi se na dva načina, putem prijenosnih linija ili pomoću antena. Budući da se signali često šalju na jako velike udaljenosti, svoju prednost imaju antene jer se valovi pružaju slobodnim prostorom. Ovisno o uvjetima rasprostiranja i frekvencijskom području potrebno je prilagoditi vrstu i parametre antene. U praksi je vrlo česta primjena dipol antena. Promjenom duljine i polumjera poprečnog presjeka dipola moguće je ostvariti različite vrijednosti njegovih parametara (dobitak, impedancija ili jakost polja) te se na taj način antena može projektirati za određenu namjenu. Na temelju provedenih simulacija dobiveni su rezultati koji pokazuju kako se mijenjaju dobitak, impedancija i jakost električnog polja s promjenom duljine i polumjera poprečnog presjeka dipola. Povećanjem duljine dipola, povećava se i jakost električnog polja i dobitak, dok za istu duljinu smanjenjem polumjera jakost polja ostaje ista, a dobitak opada. Smanjenjem duljine dipola, neovisno o polumjeru, impedancija opada do duljine poluvalnog dipola, a zatim raste do duljine poluvalnog dipola
Abstract (english)
Electromagnetic energy is transmitted in two ways – over transmission lines or antennas. As signals are often being transmitted over long distances, antennas are here at advantage because waves are emitted in free space. Depending on the conditions of emission and frequency band, it is necessary to accordingly adjust the type and the parameters of the antenna. Dipoles are commonly used antennas. By changing the length and the radius of the cross-section of the dipole, various parameter values (gain, impedance or field strength) can be achieved. As a result, the antenna can be designed for a certain purpose. The aftermath of the simulations has shown how gain, impedance and field strength change if the length and the radius of the cross-section of the dipole are changed. By prolonging the dipole, the strength and the gain of the field are changed, whereas, if the length stays the same and the radius is decreased, the field strength stays the same and the gain decreases. By reducing the length of the dipole, regardless of the radius, the impedance decreases to the length of the half-wave dipole and then increases to the length of the full-wave dipole.
