IoT-Based Wireless Microwave Power Transmission Using Rectenna

Introduction

As the technology is growing the planet is now moving toward wireless power. We will see that now days everyone prefers to use a wireless mouse or a wireless headphone. The utilization of batteries can make this possible but the matter is that too many batteries are getting used and therefore there has got to be how by which these applications can run wirelessly and the neatest thing would be if the batteries weren't used. How can this be possible? This is often the matter which we'll attempt to solve within the design. The rectanna used will convert the RF power into dc signal and rather than batteries the appliance will have a rectanna to supply the facility. Therefore we'll have a real wireless system, which has no wires and no batteries as shown Figure 1.

Iot Devices

The Internet of Things is an increasing infrastructure of internet-enabled objects starting from sensors to LED light, all aimed toward increasing control, data collection, and even automation (J. O. Mcspadden and J. C. Mankins, 2002). IoT are often a huge benefit for houses when used appropriately (W. C. Brown and E. E. Eves, 1992). To unravel the connection of the electrical problem with IoT devices are going to be using microwave power transmission technology for the smart town planning (Brown. W. C., 1984). The question stands up on how long-distance Wireless Power Electricity will change the concept of IoT (H. Matsumoto, 2002). Charging are often realized in various ways, and applications using wireless power technology are expanding to mobile and portable devices, home appliances and office equipment, and electric vehicles (Shinohara N. and H. Matsumoto, 1998). Especially, WMPT technology is beneficial in providing electric power to the web of things (IoT) devices in constrained environments. Wireless Microwave Power Transmission (WMPT), the web of things (IoT), and wireless power technology will become a corner stone within the design of latest and growth of human settlements (Hatano, K., N. Shinohara, T. Mitani, T. Seki, and M. Kawashima, 2012). In smart cities, legislation is requiring a change of old practices towards efficient use of Nevertheless, electricity distribution still relies on cables for its delivery. The novelty of the system is that IoT devices and household use WMPT for electricity supply. The energy is wirelessly supplied from an access local power plant already fixed at the highest of the house (Hatano, K., N. Shinohara, T. Seki, and M. Kawashima, 2013).
