UAV-Based Antenna Measurements: Improvement of the Test Source Frequency Behavior
Drone-based radiation pattern measurements require the knowledge of the whole test-source radiation pattern in order to reach the expected measurement accuracy. However, the radiation pattern of the onboard antenna can be highly distorted by the metal frame of the vehicle, particularly in the VHF and UHF bands, showing highly resonant behaviors. This paper presents a preliminary analysis aimed to highlight such behavior and adopt compatible solutions to minimize or avoid the pattern distortion in the frequency of interest.
