Design and optimization of the helical antenna
Zelinková, Lenka ; Olivová, Jana (referee) ; Lukeš, Zbyněk (advisor)
The thesis contains the design of helical antennas for the assigned frequencies. The theoretical design is verified by parameter calculators. The design properties were verified in the computer simulator CST Microwave studio where the antennas were optimized to the maximum gain. The antennas intended as parabola feeds are completed with the designs of parabolas and focal distances between the antennas and the parabolas. Impedance matching by a quarter-wave transformer is designed for the antennas.
