In this paper, a cylindrical coordinate system-based finite difference time domain (FDTD) method is proposed for resonant frequency computation of dielectric material loaded circular waveguide. The computation is carried out by discretizing a model of circular waveguide resonator which has the radius of 10.12mm and the length of 60mm using FDTD notation and numerically computed to determine its resonant...
This paper is about analysis and design of fiber access network systems using GEPON technology for HRB. GPON for HRB are designed to comply both for power budget and rise time budget standard. From analysis, G.652 and G.657 fiber type and also the SC connector is suitable in this design.. The design result recommended only using 1 stage splitting method with maximum splitting ratio of 1∶32 and 1∶16...
In running the activities, the Goverment requires the data and information that are real time, accurate and relevant to the field of development planning. In short, application monitoring system for fishery sea resources is a mechanism of monitoring integrated activity between staff whos are in the headquarter with staff working in each unit of work scattered throughout the territory of Indonesia...
This paper discusses the investigation of bandwidth enhancement for microstrip rectangular patch antenna by putting up multiple slots etched on the patch. The technique is proposed in overcoming the nature characteristic of microstrip patch antenna which has narrowband bandwidth response. Here, the antenna is designed to work at center frequency around 1.6GHz for GPS application. The patch of antenna...
The increase of ohmic loss which is a kind of transmission loss is unavoidable matter in optical wave radiation as well as guided terahertz (THz). Moreover, the lack of dielectric materials which have sufficiently transparency also contributes to the rising of transmission losses. As the existence of transmission loss, the quality of communication especially for optical communication will affected...
This paper discusses numerical design and experimental characterization of dualband printed monopole antenna with center frequency of 1.6GHz and 2.4GHz. The antenna that takes a shape of G letter is proposed to overcome the special need of GPS and WLAN application. The antenna which is fed by microstrip line extended from a center pin of 50Ω connector type has 2 distinct arms in different length arrangements...
An archipelago consisting of number of islands is relying on the broadband wireless technology to facilitate its telecommunication service. Mobile WiMAX (Worldwide Interoperability Mobile Access), as one of the broadband wireless technologies, is proposed to be applied as the network deployment in this paper. The network planning is designed based on cellular communication systems using hexagonal...
