Abstract
Cílem práce bylo navrhnout, vyrobit a ověřit anténní element pracující na frekvenci 70 MHz využívaný v regionálním hypertermickém systému pro léčbu nádorových onemocnění v pánevní oblasti, který se vyvíjí na FBMI, ČVUT v Praze. Dílčím cílem bylo porovnat vybraný anténní element s anténami užívanými v komerčních hypertermických systémech. Na základě odborné literatury byly navrženy a v programu Sim4Life light nasimulovány tři různé anténní elementy. Vybraná patch anténa měla oproti dipólu a vlnovodu nejlepší simulační výsledky, navíc měla výhodnější požadavky na výrobu. Patch anténa byla vyrobena a její vlastnosti podrobeny řadě měření. Naměřené výsledky se shodovaly s predikovanými hodnotami získanými ze série simulací. Z dosažených hodnot vyplynula správná funkčnost navržené patch antény, která zaručuje možnost integrace uvnitř navrženého regionálního hypertermického systému.
The purpose of this work was to design an antenna element at 70 MHz used in a regional hyperthermia system for the treatment of cancer in the pelvic region which is under development at FBMI, CTU in Prague. The partial aim was to compare the selected antenna with antennas used in commercial hyperthermia systems. Based on the literature, three different antennas elements were designed and simulated in Sim4Life light. The selected patch antenna had the best simulation results compared to the dipole and waveguide and had the most favourable manufacturing requirements. The patch antenna was created and its characteristics were studied using series of measurements. Obtained results were consistent with the data predicted from series of simulations. Achieved values showed the correct functionality of the developed patch antenna which guarantee the possibility of integration inside developed regional hyperthermia system.
