Abstract
Komunikaciju na daleke udaljenosti teško bismo ostvarivali bez prijenosa elektromagnetske energije. To je energija koju možemo slati kroz slobodan prostor pomoću antena ili putem prijenosnih linija. Antene imaju prednost kada govorimo o komunikaciji na velikim udaljenostima, jer valovi se mogu kretati kroz slobodan prostor, a antene koristimo za prijenos signala kada to nije moguće na drugi način npr. komunikacija preko planinskog terena, raketa, satelita i sl. U praksama najčešće koristi se najjednostavnija antena dipol. Antenu je lagano prilagoditi za bilo koju namjenu te joj je moguće mijenjati različite vrijednosti njezinih parametara (jakost polja, dobitak, impedanciju) promjenom duljine i ostalih dimenzija. U radu je opisan rad antena te različite vrste antena od kojih je odabrana dipol antena za ovaj rad. Za odabranu antenu opisana je njezina geometrija, parametri te način izrade simulacije antenskog niza dipola s reflektorom u ANSYS HFSS računalnom programu. Dobivene vrijednosti i rezultati simulacije poput koeficijenta refleksije, impedancije, VSWR-a i dijagrama zračenja te njihova analiza. Na izrađenom laboratorijskom modelu antenskog niza dipola s reflektorom napravljena su mjerenja u laboratoriju te su navedeni razlozi odstupanja rezultata.
Abstract (english)
Communication at far distances would be difficult to achieve without transmitting electromagnetic energy. It is the energy that we can send through free space with antenna or through the transmission lines. Antenna is an advantage when talking about communication over large distances, because the waves can move through the free space, and the antenna used to transmit signals when it is not possible otherwise, eg communication over mountain terrain, rocket, satellite, etc. In practice, we usually use the simplest antenna dipole. Antenna is easy to adjust for any purpose and it is possible to change the different values of its parameters (field strentgh, gain, impendance) by changing the lenght and other dimensions. This work describes the operation of the antenna and various types of antennas, of which the dipol antenna is selected for this work. For selected antenna are described her geometry, parameters and method of simulation of the dipole antenna array with reflector in the ANSYS HFSS computer software. The obtained values and simulation results, such as reflection coefficient, impedance, VSWR and radiation diagram, and their analysis. On the laboratory model of dipole antenna array with reflector measurements were made in the laboratory and the reasons of deviations are described.
