An Efficient Power Transfer Technique of SIMO Antennas Network

The effectiveness and optimality of the wireless electrical power transfer (WPT) technique to sufficiently charging any DC loads or electrical appliances are commonly determined by a number of factors including the type of receiving and transmitting antennas constructed, the illuminated power strength, the surrounding objects of the operated WPT environment, and the radiation pattern profiles of both receiving and transmitting antennas of which are strongly determined by their effective power illumination angle. This research work develops the novel and robust microwave WPT technique so-called MWPT and its corresponding measurement model. In practice, the MWPT architecture forms SIMO networks configuration composed of single transmitter antenna and five receiver antennas. Each receiver antenna resembles five different electronics circuit networks. The transmitter part consists of 220Volts AC power supply unit, microwave transformer, voltage multiplier, microwave magnetron unit, cooling system and AC/DC adapter and the horn antenna. The receiver part is constructed from 5 different antennas types configured in array. Each receiving antenna is directly connected to RF-rectifier circuit and all outputs may charging several different electronics parts of the specified low power consumption loads. On this manuscript, the pretty accurate voltage and power levels measurement method of which each rectified receiving parts array connected to microcontroller unit (MCU) via hall sensor and DC voltage sensor is discussed in more detailed way. MCU will continuously receive the current and voltage values from each array line and to forward them directly to PC (personal computer) through the assembled GUI. Through the step by step distance alteration of every 10 cm, in this practical testing, then the voltage and power levels profile, respectively, as the function of the transmitter and the receiver distance might be recorded and then be plotted accordingly on PC monitor.
