Directed Antennas for RFID-Based Navigation for Agricultural Unmanned Vehicles

This article examines the method of development of directed antennas for RFID technology in agricultural applications. The use of directional antennas is explained by the growing popularity of using unmanned vehicles in agriculture and with the possibility of implementing high-precision navigation of unmanned vehicles on the field without using satellite navigation. The article also covers the brief concept of use RFID technology for navigation of unmanned vehicles in agricultural applications. The article covers the modeling and physical engineering approach to make compact and robust directed antennas applicable for both identificational and navigational purposes. The conclusion is that directed antennas can be used for RFID-based precise navigation with a location accuracy of less than 1 meter.
