Design and implementation of dual band microstrip patch antenna for WLAN energy harvesting system

Since the demand for self-sustained wireless systems is increasing, there is a trend towards RF energy harvesting. It is a key solution to energize the low power systems such as the Internet of Things (IoT) devices without replacing the batteries periodically. This paper presents the design and analysis of RF energy harvesting system that consists of dual-band microstrip patch antenna operating at 2.4 GHz and 5.8 GHz, an impedance matching network, 4-stage voltage doubler and a storing circuit. The antenna is designed using ADS Agilent and sonnet suites software that provides a directivity of 5.5 dBi and 6.3 dBi at 2.4 GHz and 5.8 GHz respectively. The measured results of the fabricated antenna are well agreement with the simulated results. Simulated results show that for an input received power of 10 mW, the proposed system can provide 4.5 mW power at the output of 4-stage voltage rectifier with an overall efficiency of 45%.TÜBİTAKPublisher versio

Design and simulation of antenna with defected ground plane

Due to copyright restrictions, the access to the full text of this article is only available via subscription.In this work a patch antenna having defected ground plane is designed and simulated. Design includes two dielectric layers and some modifications at the top layer such as having a slit and a slot. Simulation results are included and discussed. Results showed that electric field total gain is 6.5 dB while input match is -18.34 at 4.72 GHz.Sonnet Suite

Serration effect on gain for microstrip E-Shape patch antenna

Due to copyright restrictions, the access to the full text of this article is only available via subscription.In this work we focus on the effect of serration on E-Shape patch antennas. We simulated 2 different E-shape antennas with the same length. The first one has serrated edge and the second one doesn't have. Then we compared the results. Sonnet Suites is used as a simulation program. At 4.22 GHz -15.2 dB return loss and 6.237 dB gain were observed
