“…We developed a very lightweight, linearly polarized antenna for the helicopter to be located on the solar panel [6] (see Figure 3). The solar panel's fixture is made of a thin layer of carbon fiber filled with closed-cell foam, with the sole purpose of being as light and strong as possible.…”

“…Meanwhile, drones are used for remote sensing and mapping in precision farming, visual inspection of infrastructure or industrial plants, or parcel delivery, to name just some of the most popular operation areas [1]. In April 2021, NASA's coaxial helicopter Ingenuity [2] accomplished its first autonomous exploration flight on the planet Mars.…”

For antenna measurements, the device under test (DUT) is usually transported to an anechoic chamber equipped with a scanner system. To measure on-site, unmanned aerial vehicles (UAVs) are a flexible solution as they can precisely maneuver a probe antenna over a surface in the DUT's nearfield region. In this work, the designed multi-rotor UAV enables electromagnetically optimal placement of the probe antenna and effective gravity center re-balacing by payload position adjustment. The onboard software-defined radio (SDR) serves as a dual-channel receiver for the dual-polarized probe and as a signal source. For phase-coherent measurements, the source signal is transmitted to the DUT via an optical fiber tethering the UAV to the ground control station. Power supply cables allow unlimited flight times. A laser-based tracking system originating from virtual reality (VR) applications measures the probe position and orientation. The developed operator software guides the UAV along a trajectory and records the irregularly distributed near-field samples. An inverse equivalent sources solver (IESS) with full probe correction computes equivalent sources for antenna diagnostics and the DUT far field. The deployed components make the system very cost-effective. Still, verification measurements demonstrate its usability and the accuracy of the results for frequencies up to several GHz.INDEX TERMS near-field antenna measurement, unmanned aerial vehicle (UAV), software-defined radio (SDR), radio-frequency over fiber (RFoF), near-field to far-field transformation (NFFFT), inverse equivalent sources solver (IESS)
