Abstract: Provided is a device for detecting precipitation conditions. In one aspect, the device includes a Yagi-Uda antenna tuned a resonant frequency and a signal generator coupled to the Yagi-Uda antenna by a transmission line, the signal generator being configured to output an excitation signal to the Yagi-Uda antenna to the Yadi-Uda antenna. The device also includes a processing system coupled to the Yagi-Uda antenna, the processing system being configured to measure the ability of the Yagi-Uda antenna to radiate a signal following excitation of the Yagi-Uda antenna by the excitation signal and, based on the measured ability of the Yagi-Uda antenna, to identify a precipitation or other meteorological condition.
