Abstract—The Wireless Power Transfer (WPT) system has enabled numerous applications in clean energy applications since their major goal is to recycle the ambient microwave energy. It is enough to drive low power consumption devices. In such system, microstrip antennas are utilized as the main component for collecting the electromagnetic energy. Antenna design is important in the proposed rectenna. The antenna absorbs the incident microwave power, and the rectifier converts it into a useful electric power. In this paper, we focus on the design of two microstrip antennas with resonant frequency of 1.88GHz and 2.45GHz to utilize in the WPT system for LTE/WLAN low power devices. The maximum return loss for each of microstrip antennas was simulated by MATLAB programming. The conversion efficiency of the fabricated antennas was measured as 38% and 35%. The results of this research can be applied in other mobile technologies.

Index Terms—WPT, rectenna, microstrip antenna, LTE/WLAN, low power.
