Slot-spiral antenna array
 Blažek, Jiří ; Pítra, Kamil (referee) ; Raida, Zbyněk (advisor)
The semestral thesis considers a Archimedean spiral slotted leaky-wave antenna as having a beneficial antenna parameters [7], thus aiming at reproducing the results so as to either validate or disprove them. The antenna is fabricated in a way of commonly known leaky-wave antenna, which is based on a substrate-integrated waveguide. Archimedean spiral slots are introduced into the substrate, creating unique structure fed by coaxial conductors. Moreover, claiming to attain beam switching ability, double-layer substrate-integrated waveguide is proposed, having four feeding ports. Both aforementioned structures are created, simulated and comparison is made using the ANSYS HFSS software.
