Mobile device for mobile communication, especially GSM communication is one of the most important thing in our daily activities. A massive mobilty and connectivity to make sure everyone is connected to each other is necessary. In a same time, electrical power needs will increase in order to support the increasingly rapid exchange of information. In this research shown the result of circular waveguide array mode TM01 measurement for RF energy harvesting application at frequency GSM 1800 MHz – 1900 MHz. Design of circular waveguide array through parameter study developed an optimum result, return loss  at frequency centre 1850 MHz. Realization of this design is measured in unechoic chamber for minimizing a reflected wave from the ambient, so it called an ideal area for waveguide parameter measurement. The measurement results return loss at freuquency 1840 MHz

This paper studies a compact wideband tree-shaped coplanar antenna which has the potential to be used for RF energy harvesting. The antenna is fabricated on a double-sided FR-4 printed circuit board using an etching technique. The effect of semi-circle patch embedded to a triangular patch has been studied. The comparison between simulation and measurement results for the return loss and radiation patterns are observed and are in good agreement. The measured return loss is in line with the simulation response where both manage to achieve lower than-10dB. A bandwidth of 3.64 GHz and 3.94 GHz were obtained in simulation and measurement process respectively. This study is an early investigation in designing the antenna for RF energy harvesting system to support green technology and sustainable development particularly for Wireless Sensor Network (WSN).

This paper presents a transparent energy harvesting antenna for a vehicle windshield application. The antenna is designed using AgHT-4 with a thickness of 0.175 mm and the glass substrate (Ɛr= 4.82) with a thickness of 2 mm. The antenna has dimensions of 46.238 x 35.4 mm. The antenna is designed and simulated in CST simulation software. It shows that the return loss of -32.76 dB obtained at 2.2412 GHz with broad directional pattern and a gain of 5 dBi. The rectifier circuit of RF energy harvesting will charge the energy storage by utilizing the ambient RF signals from the environment, convert it to the DC signal, and using the DC signal to charge the energy storage. This antenna is intended to be mounted on a car windshield to provide Wi-Fi signals to passengers
