Circularly polarized antenna array for ISM frequency band 24 GHz
Liyambo, Evans ; Cupal, Miroslav (referee) ; Raida, Zbyněk (advisor)
Tato bakalářská práce se zabývá návrhem a simulací kruhově polarizované anténní řady pro ISM pásmo 24 GHz. Kruhově polarizovaná mikropásková anténa [1] navržená pro práci na kmitočtu 45 GHz byla použita v návrhu anténní řady. Funkce použité antény byla ověřena v programu CST Microwave Studio a její parametry byly porovnány s konvenční flíčkovou anténou buzenou křížovou aperturou. Následně byla anténa modifikována tak, aby pracovala v ISM pásmu 24 GHz.

Wideband low-profile circularly polarized antenna array
Benites Ayala, Jhony Cristian ; Cupal, Miroslav (referee) ; Raida, Zbyněk (advisor)
This bachelor’s thesis is focused on the study of a novel type of wideband low-profile circular array antenna with circular polarization and high gain. The aim of this thesis is to design, optimize and implement the proposed antenna for a 5.5 - 7 GHz frequency band. The thesis deals with theoretical fundamentals in order to subsequently present the concept of the antenna. Furthermore, it describes its design and implementation stages. The antenna was designed in the full-wave program CST Microwave Studio and fabricated on dielectric substrate. Both simulated and measured property results are evaluated in the conclusion.

Loop antennas for medical applications
Zejda, Luboš ; Puskely, Jan (referee) ; Raida, Zbyněk (advisor)
This thesis is focused on the design of loop antennas for medical applications. The main goal of this thesis is to verify the functionality of published designs of broadband loop antennas, and to compare them with each other. Compared antennas are modified for available substrate and a specified frequency. Antenna with best parameters is selected, manufactured and its characteristics are compared with simulations. Design and simulation software used is CST Microwave Studio.

Circularly Polarized Antenna Array For Ism Frequency Band 24 Ghz
Liyambo, Evans
In this paper, a circularly polarized antenna array designed for operation at 45 GHz is redesigned to operate at 24 GHz. The antenna has a wide impedance bandwidth of 33 %, a 3 dB axial ratio bandwidth of 8.3 % and high gain performance. By using thicker substrates, the impedance bandwidth of the antenna was improved without changing its initial configuration. The antenna was designed in CST Microwave Studio.
