Abstract(in English) | In this paper, we performed VHF-band near-field measurement on cylindrical scanning. To suppress unnecessary radiation from RF cable and improve a measurement accuracy, we constructed a near-field measurement system using RoF transformed RF signal to Light signal. As a result, we could measure near-field of broad-beam antenna in 100MHz accurately. In addition, we derived a condition of optimal cylindrical height for improving transformation accuracy, and the condition corresponded well with the measurement result. |
