Summary: | In this paper, the circle DWS with monopole antenna is designed and studied. From previous research studies, there are design of waveguide with metamaterial by using Electromagnetic Bandgap (EBG) and Frequency Selective Surface (FSS). Yet, Defected Waveguide Structure (DWS) is not familiar to design with waveguide which is the motivation of this paper. Meanwhile, the design of waveguide with monopole antenna is not explored widely. The DWS is designed in circle shape with Ultrawideband (UWB) monopole antenna. Several factors are studied on the size, inter element spacing and number of circle DWS towards waveguide. Circle DWS with monopole antenna are analyzed through antenna parameters such as return loss, efficiency, gain and directivity. In overall, the circle DWS with monopole antenna able to operate in wide bandwidth of 8.66GHz which is suitable for UWB applications. It also achieves higher efficiency which is more than -3dB. Highest gain of 7.29dB and directivity of 8.62dBi are achieved at 9GHz and 9.5GHz respectively. The use of DWS improves the gain and directivity of low profile monopole antenna but at the same time still maintaining the its wide bandwidth. |
