Abstract: [cze] [eng]
Bakalárska práca sa zaoberá návrhom dvojpásmovej planárnej antény na textilnom substráte pre použitie vo WLAN sieťach v ISM pásmach 2,4 a 5,8 GHz vnútri automobilu. V teoretickej časti sú stručne opísané základné poznatky o vlastnostiach a typoch planárnych mikropásikových antén, spôsoboch napájania a metódach analýzy. V praktickej časti je uvedený návrh dvojpásmovej antény v programe CST Microwave Studio. Dva koncepty dvojpásmových antén navrhnuté na substráte FR4 sú transformované na 3D textil a vyladené na požadované frekvencie. Práca popisuje výrobu a meranie navrhnutých dvojpásmových antén v bezodrazovej komore a tiež vnútri auta. This bachelor’s thesis deals with the design of dual-band planar antenna on a textile substrate. The proposed antenna is tuned to the ISM band 2,4 and 5,8 GHz for application in WLAN-in-car communication. The most common types of planar microstrip antennas, their parameters, feeding methods and methods of analysis are introduced in the first part of this work. In the practical section, the design of the dual-band antenna is presented with the use of the program CST Microwave Studio. The design of two concepts of dual- band antenna made on the FR4 substrate is transformed on the 3D textile and optimised to work at desired frequency bands. After then, the thesis describes fabrication and measurement of designed dual-band antennas in the anechoic chamber and in a car.
