Design and Development of Rectenna for RF Energy Harvesting

Project Title

Design and Development of Rectenna for RF Energy Harvesting

Project Area of Specialization Wearables and ImplantableProject Summary

Energy harvesting is the process by which energy is derived from external sources and stored.

Stored energy used for small, wireless autonomous devices (used in wearable electronics and wireless sensor networks).

Rectenna is used for RF Energy Harvesting.

A rectenna is a rectifying antenna a special type of receiving antenna that is used for converting electromagnetic energy into direct current (DC) electricity.

Used in wireless power transmission systems.

Rectenna consist of:

Antenna

Rectifier

Project Objectives

As Rectenna rectify the RF Energy so it can be used for transferring the energy and can power up the small devices like low power IOT sensors.

Rectenna also used in RFID tags, Proximity cards and contactless smart card.

The objective of this project is to power up a low power sensor.

Project Implementation Method

Rectenna has two parts:

Antenna and Rectifier.

Antenna intercepts the RF signals at frequency 2.4 GHz and act as a transducer and convert the RF signals to high frequency AC signals.

Rectifier rectify the AC signal to DC. Output of rectifier is not smooth DC so a low pass filter is used to filter out the remaining pulsations and give the smooth DC at load.

Benefits of the Project

Rectennas are applicable in wireless power transfer, in wireless sensor network also power up the IOT sensors and now for modern mobile design for 5G research is on going to power up the mobile without charging the battery. Rectenna used to rectify the RF Power and continuously charge the battery.

The benefits of this rectenna is that it can power up the low power sensors so it can be implemented in wireless sensor network
