Abstract: At the time of propagation of millimeter wave, Scattering phenomenon due to foliage plays an important role as the wavelength approaches to the order of the size of the leaves and edges of leaves. It is important to estimate the propagation attenuation due to scattering when the arid zone foliage leaves and twigs size affect adversely in experimental propagation range. In this paper a 35 GHz transmitter receiver link system is used to measure the attenuation scattering pattern of tree foliage of Ber tree (Zizyphus mauritiana) of western Rajasthan region. Measurements were made to study the angular variations of the positioning of receiver unit around the target tree with trunk and canopy positions. The measurements, which were made for HH polarization configurations over a wide range of the azimuth angle, provide a quantitative reference for the design of millimeter-wave bistatic radar, high speed data communication links, point to point communication systems.
