Abstract
Ovaj rad bavi se simulacijom različitih modela loksodromske antene za frekvencijsko područje od 1 do 3 GHz unutar programskog paketa HFSS, u svrhu istraživanja svojstava ove vrste antene. Unutar simulacije promatrali su se: dijagram zračenja, koeficijent refleksije S11, VSWR, dobitak te ulazna impedancija antene. Simulacije su prvo provedene na šest različitih modela bez jezgre, gdje su antene manjeg promjera na zadanom frekvencijskom području pokazale bolje rezultate nego one većeg promjera. Nakon toga ispitan je utjecaj dielektrične jezgre na parametre antene, gdje se pokazalo da sve ispitane antene s jezgrom imaju bolje vrijednosti parametara nego one bez jezgre. Utvrđeno je da se s pravim odabirom materijala jezgre mogu dodatno optimizirati parametri antene. Ukratko je ispitana razlika između loksodromske i helikoidalne antene, gdje su prikazane sličnosti antena.
Abstract (english)
This paper deals with the simulation of different models of a loxodromic antenna for the frequency range from 1 to 3 GHz within the HFSS software package, in order to investigate the properties of this type of antenna. Within the simulation, the following were observed: radiation pattern, reflection coefficient S11, VSWR, gain and antenna input impedance. The simulations were first performed on six different coreless models, where smaller diameter antennas in a given frequency range showed better results than larger diameter ones. After that, the influence of the dielectric core on the antenna parameters was examined, where it was shown that all tested antennas with a core have better parameter values than those without a core. It has been found that with the right choice of core material, the antenna parameters can be further optimized. The difference between a loxodromic and a helical antenna was briefly examined, where the similarities of the antennas are shown.
