This synthesis algorithm will design a linear array for a specified directivity or beamwidth and a scan angle. The array is always designed so that the elements are arranged along the x-axis, with the resulting pattern being rotationally symmetric around the x-axis and the peak directivity being at the specified scan angle away from the y-z plane.

The inter element spacing is always 0.5 λ when this design algorithm is used. The excitation taper can be selected between equal excitation [Uniform], uniform side lobe level [Dolph-Chebychev] and first few side lobes uniform [Villeneuve]. The side lobe level and number of side lobes (where applicable) can then be set.
More information about how the array synthesis tool should be used can be found in ‘...
Antenna Array Synthesis in Antenna Magus’ and in ‘Help: How do I use the Array Synthesis tool?’ (located in the Antenna Magus information browser). The latter article also describes the different excitation tapers in more detail, and provides references for further research.
