Omnidirectional Beamsteering Array Antenna using Renewable Energy for Sustainable Remote Powering of IoT Devices for Continuous Monitoring

In this paper, an omnidirectional beamsteering array antenna structure is proposed that uses renewable energy to remotely charge IoT devices. A 14x14 patch array antenna was designed with the Rogers RT Duroid 5880 substrate at 2.4 GHz. Six panels of these array antennas are combined into a 3D hexagon shape for omnidirectional radiation. The top of the 3D hexagonal structure is used for a solar panel with an area of 1.8298 m$^{2}$ that can generate power up to 435 Watts.
