By increasing the parameter   , we can notice that the first side lobe reduces but the other side lobes increase. The optimal configuration is when the side lobes are at the same level and the gain is not affected too much. The reduction of SLL is explored, but it would be possible to have better results with an analytical model and optimizing the ratio. The optimized value
mm corresponds of slanted angle of the branches and       . This allows a different pattern for each
branch. Since the gain of each element has an opening (at dB) of 60 , the vertical maximal gain is not much affected, but the side lobes are in a different angle position. Hence, the struc- ture has a simulated gain of 18.5 dBi but corrects the high side lobe level of the previous design from    dB down to
dB. By controlling the angle of an individual Yagi element, the structure is similar to conformal array where arrays follow the shape of an object and therefore have each element pointing in a different direction
