Abstract
Transmit patches lie on the outer set of conductive patches that are coupled to the transmitter via the signal splitter. The receive patches lie on the outer set of conductive patches that are coupled to one or more receivers to receive a radio frequency field (e.g., fringing field) associated with the transmitted signal of one or more adjacent corresponding transmit patches. A detector is associated with one or more respective receivers for determining or estimating an attenuation of the radio frequency field (e.g., fringing field). An electronic data processor is arranged for evaluating the estimated attenuation to estimate the amount, volume, mass or flow (e.g., yield) of harvested agricultural material and/or other than grain content of the agricultural material.
