Implementation and Investigation of Rectenna for Microwave Applications

In the recent era, radio communication has a wide range of strategies like RFID schemes and wireless networks. These wireless devices locate a variety of application requests such as monitoring physical and structural quantities. These devices must be energetically autonomous. Various forms of energies like thermal, radio waves, solar etc., are used to power sensors that monitor the quantities. In this work, radio waves are used as source of energy for power sensors. The novelty lies in achieving the plans by two techniques: 1. Wireless Control transfer that involves transmitting electromagnetic energy from intentional or dedicated transmitter and then converting the obtained energy into DC. This is accomplished by using a rectenna (rectifier + antenna). 2. The second part is harvesting the energy that is obtained by using this rectenna. A multiband frequency rectenna is implemented for energy gathering of the spill. The planned rectenna proficiently crops energy at 3 dissimilar incidences. The design of the antenna is pretended using ADS software and is fabricated using FR-4 substratum. The antenna captures the RF signal. The rectifier then converts the signal to DC power. This DC power is utilized to energize low power devices. Here, the power obtained with such a design is found to be very low so the result is depicted using FFT signal. Based on the results, the measured and return loss of the antenna design produces convincing and required results.
