# Here, we plot the antenna element’s directivity in the horizontal plane at zero elevation.

# Here, the 'drawRadiation' method is used again to generate a 3D plot of directivity.
# This time, however, we set the angular resolution to 2°, which makes the plot render faster
# but slightly coarser than before. (The default angular resolution is 1°.)
