This article also describes the different excitation tapers in more detail, and provides references for further research. More information about how the array synthesis tool should be used can be found in the array article in the information browser. The specification of the scan angle will introduce an inter element phase offset in the excitation. For higher gain designs, the first 5 side lobes will be -20dB below the main beam directivity. If a directivity of less than 20dB, or a beamwidth of greater than 20 °, is specified, all the side-lobes will be equal and -20dB below the main beam directivity. The inter element spacing is always 0.49λ when this design algorithm is used.
