Abstract :
The determination of the loading impedances loaded on a straight wire antenna in order to realize the desired beam tilting and low sidelobe level is discussed. We obtained the loading impedances from the desired characteristics in a straightforward manner. Moreover, we obtained the desired characteristics using a reactive load which is easy to realize.
