Using cable as power transmission medium caus e problem in flexibility and aesthetics. Wireless power transmission for charging handphone released nowadays still using antenna with radiation pattern focus in one direction, that is just toward the top, and if the ant enna was shifted then power transmitted will be lose. The purpose of this research is to produce wireless power charger system used for charging handphone power using resonator based on omnidirectional antenna and test the performance. The device in this research was designed in two main part, that is transmitter and receiver. In transmission section, there is power supply used for supplying power to oscillator to generat e oscillating signal in the form of electrical power to be transmitted to rec eiver via antenna in the form magnetic field. In receiver section, receiver antenna received the power transmitted that is still in the reach of magnetic field generated by transmitter. The power that is still in the form of oscillating signal, then stabilized for the purpose of handphone power using rectifier and voltage regulator. Design has been made successfully to the form of handphone battery power wireless charger using omdirectional antenna which consist of two main part, that is transmitter and receiver. The transmitted power is 3.058 watt with frequency 714 KHz, and receiver received the power and then stabilized the signal to produce output power 58.706 miliwatt. This device can transmit power in all directions horizontally (angle 360°). This device also tested with some kind of obstacle, with the res ult almost all obstacle still could transmit the power except metal.

“…There are already some scholars who have studied in this promising field, such as the node design of rechargeable wireless sensor networks (RWSN) [11,12], mobile chargers (MC) deployment [13,14], MC path planning, cooperative charging [15,16], multi-hop charging [17,18] and so on. Some progresses have also been reported for coal mines, such as the propagation characteristics of wireless charging electromagnetic wave [19], node scheduling [20], distributed cooperative charging [21], cross-layer optimization [22], directional antenna charging [23], opportunity charging [24] etc. To the best of our knowledge, there are no wireless charging solutions for coal mines faces.…”

The working face is the most dangerous place of coal mines, and it is difficult (even impossible) to replenish energy by replacing batteries of sensor nodes in the working faces. This paper presents a wireless charging method for this scenario that is composed of two sub methods called mining charging and maintaining charging, respectively. Mining charging provides opportunistic charging services during the process of coal cutting through two airborne Mobile Chargers (MCs) installed on the two ends of the shearer and two portable MCs carried by shearer drivers. Maintaining charging provides opportunistic charging services for nodes in the charging radius when scraper conveyor repairmen and hydraulic support repairmen check or repair equipment, with each repairman carrying one portable MC. Simulation results show that both mining charging and maintaining charging can give energy replenishment for nodes in coal faces. When charging power of MCs is greater than or equal to 5.2 W, the first row of nodes can work sustainably. If the energy requirements of the second row of nodes are also met, the charging power of MCs cannot be less than 12 W.
