Integrated antenna design in millimeter wave frequency and effect of surface finish material on antenna performance

The popularity of millimeter wave applications has been increasing lately. One of the main reasons for this increase is the wide frequency band. Thus, data can be transferred at high speed. The ever-increasing use of smartphones and tablets continues to increase data traffic. New approaches are needed to guide and manage increased data traffic. Applications that work in millimeter wave band are needed as solutions. As the data traffic created by human beings increases, the importance of communication in millimeter wave frequency bands increases. Working in millimeter wave frequencies include vehicle radar systems, V2X applications, wireless communications, etc. are used in applications. Working at millimeter wave frequencies has several advantages. For example high data transmission capacity in a short period of time, designed analog RF layer, antenna and other passive structures are small due to the short wavelength. There are disadvantages as well as advantages. The most important of these disadvantages is the high atmospheric losses of the millimeter wave frequencies. In this thesis, it is aimed to use two structures which can be used in wireless communication applications, compatible with integrated circuits, which can work on millimeter wave frequencies with planar double exponentially tapered slot antenna and balun. In addition, the efficient surface finishing materials which can be selected in order to prevent oxidation of copper and circuits in the circuits and antennas designed on the PCB at high frequencies and to avoid signal losses are examined and their performances are compared.
