Abstract:

A scale model investigation to determine the radiation pattern of a simple monopole located at the center of a Wullenweber Array is described. In constructing the models, the Wullenweber screens were modeled as conducting cylinders, although the actual screens are made up of a large number of vertical cables spaced close together in terms of the wavelengths being considered. The use of a solid conducting cylinder in the model is further justified by the fact that a vertically-polarized radiator symmetrically located at the center of the structure was to be used. Thus the currents induced in the screen would essentially be vertical and the solid screen should behave essentially as would a screen of vertical wires. Two different screen diameter to screen height ratios DH were considered. Author
