|Title:||High frequency antenna design||Authors:||Ong, Hui Fang||Keywords:||DRNTU::Engineering::Electrical and electronic engineering||Issue Date:||2017||Abstract:||This research paper presents a study of designing a high frequency antenna aimed to reduce valuable land use by using liquid metal materials apart from the conventional materials used in the design and fabrication of antennas. High Frequency antenna ranges from 3MHz to 30MHz and are usually large in size due to their long wavelength. The design of introducing liquid metal materials hopes to provide a wider range of flexibility with comparison to the conventional antennas which is controlled in a predictable manner. The antenna designed in this study is of quarter wavelength monopole design aimed at 15MHz. Computer Simulation Technology (CST) software was used throughout the entire duration of the Final Year Project to simulate the multiple designed antennas. The liquid metal chosen for this research is Graphene which is a comparable good conductor thus a suitable material for this research. Within this research paper presents various bending possibilities to observe a pattern in the manipulation of directivity of the antenna. The objective of bending the antennas is to simulate real life configurations of manipulations. This research paper verifies that through the bending of antenna, it is possible to manipulate the directivity of the antenna. Recommendations was made to improve on the performance of the antennas. Therefore, with more research and experiments, it is possible to improve on the directivity such as allowing the user to specify a more precise area of directivity.||URI:||http://hdl.handle.net/10356/71082||Rights:||Nanyang Technological University||Fulltext Permission:||restricted||Fulltext Availability:||With Fulltext|
