Abstract
Wireless sensor network has been developing rapidly. Internet of Things (IoT) is a major role for the next generation of wireless communication system. However, the power consumption and lifetime of the battery are a limitation for the IoT device. Wireless Power Transfer (WPT) is a promising technology to solve the problem due to it can be the ubiquitous power source for the IoT devices by provide the energy via the propagation of radiowaves. The 2.45 GHz ISM is a popular frequency bandwidth which widely used in WiFi application which make it easy to use. The performance of the propagation can evaluate by various parameter. Receive power is use to analyze the efficiency of the radio frequency transmission. Therefore, this paper has been evaluated the WPT measurement data with difference separate distance between antennas at 2.45 GHz. By using the meander line antenna as the transmit antenna and receive antenna. Vector network analyzer (VNA) is used to measure and record the transfer function. The receive power which analyze the measurement data by using link budget equation. The results have shown good agreement between the simulation and measurement result which have the average of measurement result less than the simulation result around 2 dB.
