Summary:
The change of the radio wave propagation loss in 920-MHz band was examined as bushes in a farm grew higher. Received Signal Strength Indicator (RSSI) was measured as a function of the distance between the transmitting antenna (Tx) and the receiving antenna (Rx) in a 50 x 50 m mulberry field. Tx and Rx were placed at a height of 1.5 m. Moreover, the horizontal and vertical polarizations were measured. The results revealed that the path loss increased in both horizontal and vertical polarizations as bushes grew up and that the horizontal polarization could be less affected by bushes than the vertical polarization.
