In the last years, an innovative system to measure the radiation pattern of VHF and UHF antennas for radio astronomy has been presented. The system exploits a small Unmanned Aerial Vehicle as a radio frequency test-source to characterize receiving antennas and arrays on the ground. In this work, a broadband (50 MHz - 650 MHz) test-source antenna has been designed in order to both improve the measurement accuracy at the lowest operating frequencies and enable multi-frequency measurements.

Abstract
In the last years, an innovative system to measure the radiation pattern of VHF and UHF antennas for radio astronomy has been presented. The system exploits a small Unmanned Aerial Vehicle as a radio frequency test-source to characterize receiving antennas and arrays on the ground. In this work, a broadband (50 MHz - 650 MHz) test-source antenna has been designed in order to both improve the measurement accuracy at the lowest operating frequencies and enable multi-frequency measurements.File in questo prodotto:
