Abstract

In this study, a new material from recycle carbon based material had been introduced as a starting material in ceramic fabrication process to design a dielectric resonator antenna (DRA). In ceramic manufacturing, metal material such as copper and titanium as starting materials were difficult to be moulded and required higher production cost. Hence, the performance of a non-metal material which was carbon based material in wireless application had been investigated. This study involved implementation of ceramic fabrication process by determining the correct amount of carbon powder and binder to be pressed and appropriate sintering temperature for carbon. Next, dielectric value of carbon based ceramic would be measured and a DRA was designed in CST Microwave Studio with microstrip coupling feeding mechanism to excite the DRA. Furthermore, binder was an important material in pressing process and the wax in this study showed a good result to hold the carbon particles to form a pellet. Dielectric constant of carbon based material could be improved in the future so the size of DRA could be reduced. As conclusion, carbon based material was a good candidate to be used in DRA. For further works and improvements, the pellet could be used as a resonator in DRA circuit to determine the experimental result besides running a simulation by CST Microwave Studio. Other than that, dielectric value of carbon based material also could be improved by controlling the sintering condition and sample preparation.
