Circularly polarized antenna array for ISM frequency band 24 GHz
Liyambo, Evans ; Cupal, Miroslav (oponent) ; Raida, Zbyněk (vedoucí práce)
This thesis deals with the design and simulation of a circularly polarized antenna array optimized for operation in the 24 GHz ISM frequency band. A circularly polarized microstrip antenna element [1] designed for operation at the frequency 45 GHz, which was used in the antenna array design, was first verified for proper functionality in CST Microwave Studio, and its parameters were compared with a conventional patch antenna excited by a cross aperture. The microstrip antenna element was then redesigned to operate in the 24 GHz ISM frequency band for use in the antenna array design.
