| Abstract: | The mechanical and electrical descending beam patterns used in mobile communication base station smart antenna which composed of radiating elements of array with inclined polarization are computed and discussed. The results indicated that the mechanical descending beam patterns are more benefit to communication than the electrical descending for free space patterns in a vertical plane, direct incidence ground field strength distributions and ratios of cross polarization in a horizontal plane. But the electrical descending beam patterns are more convenient than the mechanical descending for out doors construction and network online debugging. |
