|Title:||Miniaturized VHF antenna using LTCC technology||Authors:||Salim, Hartarto.||Keywords:||DRNTU::Engineering::Electrical and electronic engineering::Antennas, wave guides, microwaves, radar, radio||Issue Date:||2010||Abstract:||Very High Frequency (VHF) antenna has frequency range from 30 MHz to 300 MHz and generally the sizes of electrically small antennas in this frequency range are large. Electronic devices and communication equipment today are made so compact that miniaturization of components is critical, especially for small and broadband antennas. It is of immense need to miniaturize components which are resourceful for modern communication systems. Various kinds of antennas have been studied based on the fundamental limitations of electrically small antennas. Although the former electrically small antennas are electrically small in size, they have narrow band characteristics. Antenna minimization at VHF frequency is of particular interest due to the much larger size and often non-conformal installations of these antennas. Miniaturization is often achieved by using dielectric or magnetic materials and less often lumped loads. Impedance matching over broad frequencies is also necessary and may be accomplished using antenna shaping and matching circuits at the antenna feed. In using such circuits at the feed, the goal is to cancel the antenna reactance and transform the antenna resistance to that of the matching network. The objective of this final year project is to study on miniaturized VHF antenna using Low Temperature Co-fired Ceramic (LTCC) technology implementation. The antenna has been designed using High Frequency Structural Simulator (HFSS). The designs are simulated to predict the performance of the miniaturized VHF antenna.||URI:||http://hdl.handle.net/10356/40845||Rights:||Nanyang Technological University||Fulltext Permission:||restricted||Fulltext Availability:||With Fulltext|
