Abstract: Millimeter wave range is of interest for scientist as demand of communication bandwidth and channel capacity are increasing day by day. By previous research it was concluded that rate of attenuation decreases with foliage depth. This decrement is due to coherent interference between scattered field components. In this paper, an attempt is made to compare actual attenuation with linear theoretical attenuation when signal prevails through foliage depth in desert region. An outdoor set-up is installed in desert region of Thar, India to measure attenuation in millimeter wave of 35GHz. By computations using Simpsons one-third method it is observed that 25.5 % of scattered signal exhibits coherency when environmental conditions are in dry phase while in wet environmental conditions (after 2 hours of rain) 21.07 % of total scattered signal exhibits coherency. In phase relation in scattered field components is due to collectiveness of leaves which scatters the signal.
