An Overview about Microstrip Antenna for Energy Harvesting in Agriculture

Interest in implementing wireless sensor networks across a variety of industries has been on the rise in recent years. Ecological monitoring, inventory tracking, healthcare, animal tracking and control are just few of the many uses for network systems made up of spatially distributed sensor nodes. One promising use for WSNs is in the agricultural industry, where they are placed in fields to track environmental factors including soil moisture, mineral concentration, and temperature. It is possible that the information gathered by these sensors might be utilized to optimize water and fertilizer usage, forecast agricultural yield, and enhance crop quality. Battery life is a major issue for agricultural wireless sensors. The batteries that power these sensors often have a finite energy capacity and a short service life. This necessitates their eventual replacement. Because the sensor devices must be dug up, the expense of replacing their dead batteries is also prohibitive. Additionally, there is the problem of where to put all those old batteries. Heavy elements found in batteries, such as mercury, lead, and cadmium, can cause health and environmental risks if disposed of incorrectly in landfills. Energy harvesting, which is the process of collecting energy from the environment around the sensors and converting it into electrical energy that can be used, has the potential to be a long-term solution to the problems that have been identified. Wireless energy transfer is currently advised above collecting energy from radio frequencies (RF) due to concerns about its impact on the environment. It is possible to use RF energy harvesting to not only resupply the power that is required to operate the soil sensors, but also to provide a more regulated and predictable power source. This is an advantage over other potential methods of gathering energy, as it is possible to use RF energy harvesting to resupply the power that is required to operate the soil sensors. The revolutionary practice of RF energy harvesting has the capacity to supply power to thousands of wireless sensors despite the great distances that separate them, all while retaining the scalability that allows the user to maintain control. The devices that make use of this wireless technology can be completely sealed, incorporated into structures, or made mobile without the requirement of the usage of batteries in any of these scenarios.
