The document discusses a proposed BTS Hotel system solution to improve Telkomsel's signal coverage at UGM Campus in Yogyakarta, Indonesia. It involves installing both outdoor and indoor coverage solutions using feeder-less BTS and camouflaged antennas. The proposed architecture includes outdoor antennas connected to a BTS Hotel with battery backup, connected via fiber optic cables. Indoor coverage would be provided by installing individual BTS units in 16 campus buildings. The project timeline and roles of the various organizations involved are also outlined.
Developing an actual very high frequency antenna using genetic algorithmseSAT Journals
Abstract Antenna for the 88-108MHz Very high frequency (VHF) broadcast audio frequency-modulation (FM) band. The antenna is intended tofit in the flat area inside the head-band of an over ear hearing-protector headset. The space for the antenna is limited by an existing head-band design, where the unused internal area is the space studied in this thesis. A genetic algorithm is described for the multiple objective optimization of the antenna matching and radiation pattern optimization. The results of multiple genetic algorithm evaluations are described, and possible further improvements outlined. Progress is made on the development of the antenna. The antenna radiation pattern is evolved in desirable way, but a difficulty in solving the antenna matching problem is identified. Research for resolving the antenna matching problem is described in this paper Keywords: Antenna, Modulation, Genetic Algorithm, Frequency, Head-Band, Very High Frequency Broadcast.
Optimization of 14 nm double gate Bi-GFET for lower leakage currentTELKOMNIKA JOURNAL
In recent years, breakthroughs in electronics technology have resulted in upgrades in the physical properties of the metal oxide semiconductor field effect transistor (MOSFET) toward smaller sizes and improvements in both quality and performance. Hence, the growth field effect transistor (GFET) is being promoted as one of the worthy contenders due to its superior material characteristics. A 14 nm horizontal double-gate bilayer graphene FET with a high-k/metal gate is proposed, which is composed of hafnium dioxide (HfO2) and tungsten silicide (WSix) respectively. It is simulated and modelled using silvaco ATHENA and ATLAS technology computer-aided design (TCAD) tools, as well as the Taguchi L9 orthogonal array (OA). The threshold voltage (VTH) adjustment implant dose, VTH adjustment implant energy, source/drain (S/D) implant dose, and S/D implant energy have all been investigated as process parameters. While the VTH adjustment tilt angle and the S/D implant tilt angle have both been investigated as noise factors. When compared to the initial findings before optimization, the IOFF has a value of 29.579 nA/µm, indicating a significant improvement. Findings from the optimization technique demonstrate excellent device performance with an IOFF of 28.564 nA/µm, which is closer to the international technology roadmap semiconductor (ITRS) 2013 target than before

Design of a dual-band antenna for energy harvesting applicationjournalBEEI
This report presents an investigation on how to improve the current dual-band antenna to enhance the better result of the antenna parameters for energy harvesting application. Besides that, to develop a new design and validate the antenna frequencies that will operate at 2.4 GHz and 5.4 GHz. At 5.4 GHz, more data can be transmitted compare to 2.4 GHz. However, 2.4 GHz has long distance of radiation, so it can be used when far away from the antenna module compare to 5 GHz that has short distance in radiation. The development of this project includes the scope of designing and testing of antenna using computer simulation technology (CST) 2018 software and vector network analyzer (VNA) equipment. In the process of designing, fundamental parameters of antenna are being measured and validated, in purpose to identify the better antenna performance.
