In this study, it is aimed to obtain two different asymmetric radiation patterns
obtained from antennas in the shape of the cross-section of a parabolic
reflector (fan blade type antennas) and antennas with cosecant-square radiation
characteristics at two different frequencies from a single antenna. For this
purpose, firstly, a fan blade type antenna design will be made, and then the
reflective surface of this antenna will be completed to the shape of the
reflective surface of the antenna with the cosecant-square radiation
characteristic with the frequency selective surface designed to provide the
characteristics suitable for the purpose. The frequency selective surface
designed and it provides the perfect transmission as possible at 4 GHz
operating frequency, while it will act as a band-quenching filter for
electromagnetic waves at 5 GHz operating frequency and will be a reflective
surface. Thanks to this frequency selective surface to be used as a reflective
surface in the antenna, a fan blade type radiation characteristic at 4 GHz
operating frequency will be obtained, while a cosecant-square radiation
characteristic at 5 GHz operating frequency will be obtained.
