S Band Antennas for Cubesat Satellites
Bekeč, Alexander ; Cupal, Miroslav (oponent) ; Urbanec, Tomáš (vedoucí práce)
This bachelor’s thesis is dedicated to antennas designed for use onboard miniaturized satellites CubeSat. The main goal of the thesis was to examine suitable antennas working in the S-band for use onboard this type of satellites, create their models and simulate them in the software ANSYS HFSS together with the CubeSat frame to find out its impact on the characteristics of antennas. One of these antennas was constructed together with CubeSat frame and measured in the RF anechoic chamber. Besides these, different types of satellite attitude stabilisation were examined, along with their influence on communication with ground station. Minimal half power beamwidths of antennas were analysed for both studied types of single axis stabilisation with consideration of communication with ground station located in the city of Brno.
