This paper describes the detailed RF propagation measurements and modeling in a Japonica paddy field of grain filling stage. From the viewpoint of practicality, a commercially available wireless communication module equipped with a small pattern antenna was used for the experimental apparatus. Detailed measurements of RSSI were made considering the various clutter effects such as vegetation, reflection, and scattering. The antenna height was chosen as 55, 105, and 155cm against to rice plant height of about 90 - 100cm. The measurement results are discussed based on the propagation phenomena associated with three kinds of propagation models. As a result, these models fit well depending on the antenna height respectively, where two of them are conventional and the other is newly developed in this study. |
