At spacings below ………, the null fills in and the reduction in sideways rejection is much less, as shown in the ………. Case in Fig 14-3. For spacings greater than ………. , the side radiation actually increases----to a maximum at a full ….. , since the energy arriving at the other elements is now 360 องศา out-of-phase, Which is the same as being in-phase. Above………. Spacing, arrays have significant lobes at other azimuths, and thus most systems use spacings less than ……….. . One exception is a spacing of ………….. , Which offers the maximum broadsind gain at a cost of some spurious lobes. Its azimuth pattern is shown in Fig 14-4.
