Multiband embroidered antennas
Fraj, Lukáš ; Olivová, Jana (referee) ; Raida, Zbyněk (advisor)
This thesis is engaged into the designing embroidered dipole multiband antenna. Numerical models of the antenna, operating at GSM 900 Mhz, PCS 1900 MHz and WLAN 2450 MHz bands, were designed using finite-element ANSYS HFSS software. Simulations of this antenna in the free space and near the human body, interpreted by numerical model, are compared with each other. Afterwards the antenna is optimized for 900 MHz, fabricated and measured. All achieved results are compared with the pattern.

Wearable antenna operating in proximity of human body
Jakubíček, Marek ; Pokorný,, Michal (referee) ; Vašina, Petr (advisor)
This thesis describes the possibilities of wearable antennas and the basic properties description. Numeric model for ISM 2,4 GHz band is created by CST Microwave Studio®. The thesis also deals with the human body proximity effect by two models of human tissue. The effect of flexibility to antenna parameters is evaluated. Several samples of the antenna has been created and measured. Obtained results has been compared with numeric model and with the literature.
