Abstract
UWB sustavi su bežični sustavi koji se temelje na korištenju signala širokog spektra te male spektralnom gustoće snage. Jedna od najvažnijih komponenata bilo kojeg bežičnog sustava je antena. Zadatak ovog rada bio je izraditi UWB antenu za frekvencijski opseg od 500 - 2000 MHz. Za izvedbeni model antene odabrana je kružna unipol antena otisnuta na podlozi napajana mikrotrakastom linijom. Rad antene simuliran je u programu HFSS. Nakon izrade simulacijskog modela koji je zadovoljavao sve zahtjeve izrađen je laboratorijski model antene. Mjereni su koeficijenti refleksije, impedancija antene te dijagrami zračenja u horizontalnoj i vertikalnoj ravnini. Mjereno je na dvije rezonantne frekvencije dobivene simulacijskim modelom. Nakon mjerenja uspoređeni su rezultati simulacije s rezultatima mjerenja te je objašnjeno zašto dolazi do odstupanja u rezultatima.

Parallel abstract (English)
UWB systems are wireless systems based on using signals with wide spectrum and low spectral power density. One of main components of any wireless system is antenna. Main goal of this work was to construct UWB antenna for frequency band 500 - 2000 MHz. The chosen type of antenna is printed circular disc monopole fed by microstrip line. The antenna was simulated in software HFSS. After making a simulation model of antenna which fulfilled all requirements, the laboratory model of antenna is made. Parameters which were measured are reflection coefficient, antenna impedance and radiation pattern. Radiation pattern was measured in horizontal and vertical plane. The frequencies on which measurements were conducted are two resonant frequencies of simulation model. After measurement, the results of simulation were compared with measurement results and reasons of deviation were explained.
