Abstract

In this era of globalization, there are varous technologies that are increasingly sophisticated and many that furthur facilitate communication between people. With this improvement in communication, there are various breakdowns thaht have been done in communication. Among them is communication for civilians and also for the military. Communication that establish for the population is where, the communication done by the telecommunication company launch a telco which allows the residents to communicate with each other. In the context of military, in order to maintaiin the national security, various technologies are used to avoid enemy attacks. Communication in the military necessarily prioritizies classified information. Next, telecommunications is so important for both parties. Thus there is the X-Band frequency which is reserved for communication between the people and used in the military with a frequency range of 8GHz to 12GHz. The objective of this paper is to design a waveguide in the range of X-Band frequency to be used in measuring the results of Scattering Parameters for reflectarray cell unit. Next, to optimize the sze of the waveguide and unit cells measurements in reducing the cost of fabrication and materials used in designing the waveguideguide and unit cells reflectarray. In addtion, analysis was performed on both design objects in various types of materials in order to find and discover ways to reduce the design cost and size of waveguide shape. In this case, the process for designing a waveguide for a reflectarray is to design a unit of cells and waveguide in the X-Band frequency range. Next, optimize the waveguide size to find out the differences in the use of different materials. Fabrication is done for unit cells and waveguide to see the Scaterring Parameters results using Vector Network Analysis, then observe the differences based on simunlations and measurement results made. As a results, it can be seen from Scattering Parameters in dB will be around 10GHz. This paper shhows the processing that takes place in designing a waveguide in the X-Band frequency range 8GHz-12GHz.
