Antena integrated to automobile seat
Gulda, Tomáš ; Mrnka, Michal (referee) ; Cupal, Miroslav (advisor)
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.

Woven antennas
Fikar, Jan ; Pítra, Kamil (referee) ; Raida, Zbyněk (advisor)
The thesis is aimed to design textile antennas that can operate in the ISM band 5.8 GHz. Attention is turned to practical exploitation of these antennas under regular conditions. Variations of the bandwidth of the antenna due to washing and waterproofing will be observed. Finally, the impact of the proximity of living tissue on the parameters of antennas will be studied.

Wearable Circularly Polarized Rectangular Ring-Slot Antenna With Chamfered Corners
Vašina, Petr
This paper deals with a circularly polarized rectangular ring-slot antenna with chamfered corners designed for 5.8 GHz ISM frequency band for off-body communications. The antenna, originally designed for conventional microwave substrate, has been redesigned for a soft-shell textile material to create its wearable version. For its manufacturing, the screen printing technology has been exploited. Experimental results prove that the wearable version of the antenna located on a muscle equivalent phantom achieves the impedance bandwidth more than 6.3 % for the reflection coefficient less than -10 dB, the axial ratio (AR) bandwidth 1.7 % for the AR less than 3 dB and the RHCP gain more than 6.0 dBi.
