Effect of Unmanned Aerial Vehicles for Electromagnetic Field Measurement on Near Field of High-frequency-Band Monopole Antennas

In recent years, the number of studies on the applications of unmanned aerial vehicles (UAVs) to communication and measurement has been increasing. A UAV is difficult to navigate in the narrow land of Japan, and a dedicated device is required for exchanging data with the UAV. Therefore, herein, we aim to construct an environment where amateur radio engineers without a large measurement facility and expensive equipment can easily measure radiation patterns. Moreover, we examined the effect of UAVs on the near field of a high-frequency antenna.
