A Miniaturized Conformal UWB Antenna For UAV Application

Project Area of Specialization Information & Communication TechnologyProject Summary

In recent years, Unmanned Aerial Vehicles (UAVs) have been used for exploration of the earth in emergency and surveillance catastrophic situations, for which it is necessary a signal detection system. This application usually requires hardware to send high data transmission in ultra-wideband (UWB) spectrum. The communications with UAVs are a big challenge because the instability and the drag issues when the drone is moving. Furthermore, the UAV antenna system should be ultra-wideband, low profile, and aerodynamic. In addition, it should have a directive pattern to the earth and spatial diversity. Typically, the UAV antennas are flat square patches and dipoles, which cannot be used for UWB applications. Otherwise, the implementation of UWB technology on UAVs is feasible. The design problem of this research consists in finding out a UWB antenna design that can be located easily on the UAV with spatial diversity for the above UAV application. The antenna structure should be conformal to avoid drag problems that the UAV suffers during the flights

This project proposes a novel antenna design for UWB communications. The main advantages of the proposed antenna are the aerodynamic shape for quadcopter drones, low-profile, and UWB operation. With this geometry. This new antenna is a good alternative for UWB systems with drones because there exists the possibility to use four antennas on the aircraft. This can avoid generating interferences. The proposed antenna can be mounted in a real aircraft structure and provided a similar performance of the simulated antenna.
