Abstract:

Measurements taken on a log periodic antenna are described and the relationships found between the physical parameters and the electrical performance of the antenna are pointed out. This information was combined into a design nomograph. A special variable-parameter log periodic antenna was constructed such that the basic design parameters could be varied over a wide range. Measurements for many different values of these parameters revealed, among other things, that the element spacing-to-length ratio must not exceed 1.3, and that an alphapsi ratio of approximately 1 or higher must be maintained for proper operation of the antenna. All information gathered was combined into a nomograph to facilitate design work on log periodic antennas. Author
