    Abstract: This paper presents the First report of an ongoing to study the effects of trees on radio signals at microwave frequencies. The effects of vegetation media on the planning and design of radio links at microwave and Microwave frequencies are considerable and must be accounted for by radio system operators and users. Measurements have been made to de... Show More
