20.500.12556/DKUM-42367 OPTIMIZACIJA ODDAJNIH ANTENSKIH SISTEMOV OPTIMIZATION OF TRANSMITTING ANTENNA SYSTEMS Diplomsko delo zajema projektiranje antenskih sistemov. Ker v fazi projektiranja težimo k optimizaciji antenskih sistemov, je v diplomskem delu prikazano, kako priti do boljših rezultatov antenskega sistema. Optimizacija antenskega sistema se izvaja z ustreznim dimenzioniranjem povezovalnih kablov. S tem pripomoremo, da antenski sistem obratuje z maksimalnim izkoristkom in se ne pregreva. Zelo pomembno je tudi, da antenski sistem ne seva v zrak. Na naklon sevanja lahko vplivamo z mehanskim naklonom anten oziroma z ustrezno električno dolžino kablov. Vse te lastnosti v fazi projektiranja simuliramo s programom Emlab, ki ga je razvilo podjetje Aldena. Zaradi velike konkurence na trgu je zelo pomembno, da antenskih sistemov ne predimenzioniramo, saj bi to pomenilo večjo ceno sistema, s tem pa bi morebiti lahko izgubili posel. Thesis describes the design of antenna systems. Since we aim at the design stage to optimize the antenna system, the thesis describes how to get the best results of the antenna system. Optimization of antenna system is implemented with appropriate sizing of connecting cables. This helps that the antenna system operates at maximum efficiency and does not overheat. It is also important that the antenna system is not radiating in the air. The angle of radiation can be affected by a mechanical angle of antennas and with adequate electrical length of cables. All of these characteristics are being simulated in design phase with Emlab program, developed by Aldena. Due to high competition in the market it is very important that the antenna system is not oversized, because this would mean higher cost of the system and thus could potentially cause losing business. antena antenski sistem optimizacija oddajnih antenskih sistemov digitalna prizemeljska televizija (DVB-T) antenna antenna systems optimization of transmitting antenna systems digital broadcasting television (DVB-T) true true false [J.
