Note that the design objectives have been met. The main beam is less than 26⁰ wide on each side and the gain is 12.5 dBi, a very respectable signal. Notice something else, the spurious sidelobes. These have cropped up because of the outer elements at 45⁰ off axis on each side. For many applications these extra lobes are a small price to pay for the additional gain of the larger array. There are some applications, however, in which such types of sidelobes are completely unacceptable. For example, in a radar system with a rotating antenna, a single aircraft would seem to appear at different azimuths (with different strengths), resulting in false alarms and mistargeting of weapons. A modern digital system with processing can be used to eliminate the false targets; however, it is also possible to eliminate them through a change to the antenna design based on adjusting the currents in each element.
