Measure antennas for GSM and Wi-Fi bands
Hurt, Martin ; Láčík, Jaroslav (referee) ; Mikulášek, Tomáš (advisor)
This bachelor’s thesis deals with the design of the measure antennas for GSM900, GSM1800 and Wi-Fi bands. In the first step, the work is focused on the design of two antennas for GSM900/GSM1800 bands and for Wi-Fi band in the CST Microwave Studio. In the second step, both antennas are fabricated and validated by the measurements. The measured results of the realized antennas are affected by asymmetric currents. In the work, the possibilities of the eliminating of the currents are discussed in detail.

Circularly polarized serial antenna array
Hurt, Martin ; Tkadlec, Roman (referee) ; Kufa, Martin (advisor)
This work focuses on the design circularly polarized serial antennas array operate in the ISM band (5.725 GHz to 5.875 GHz). Design of antennas is divided into three parts. In the first part is designed feeding system, followed by two types of circularly polarized antennas and at the last point, these components are integrated. Furthermore, these antennas are fabricated, measured their parameters and used for experimental verification of the influence of multipath transmission in-vehicle.
