Antena integrated to automobile seat
Tato bakalářská práce se zabĂ˝vá návrhem antĂ©ny integrovanĂ© do sedadla automobilu. Seznamuje se základy technologie RFID a jeho principem. KonkrĂ©tnÄ› se práce zabĂ˝vá návrhem tagu pracujĂcĂho v pásmu UHF. Tag byl navrĹľen v programu CST Microwave studio, kde byly provedeny simulace, k ověřenĂ základnĂch vlastnostĂ antĂ©ny tagu jako jsou napĹ™Ăklad ÄŤinitel odrazu a smÄ›rová charakteristika. Jsou zde takĂ© simulace vlivu sedadla automobilu na vyzaĹ™ovacĂ charakteristiku. Dále je zde popsána vĂ˝roba antĂ©ny na textilnĂm substrátu a jsou zde změřeny jejĂ vlastnosti.This thesis is focused on the design of the antenna integrated to automobile seat. Thesis explains the basics of RFID technology, and how RFID works. Especially explains the design of tag, which works in the UHF band. The tag was designed in the CST Microwave studio, where simulations were realized to verify basic properties of the tag such as S11 parameter and directivity. The thesis also contains simulation of the impact of automobile seat on the directivity. Here is the description of how the antenna was made on a textile substrate and here are also measured properties of the antenna.
