Planar: Specify the layout directly

This algorithm allows the specification of the array and its excitation directly. Antenna Magus does not adjust the array layout at all to achieve specific electrical objectives. It is useful to use this to evaluate a custom array layout, using the array routines in Antenna Magus. The elements of the array are arranged in the x-y plane, centered on the z-axis.

An example of a customised planar array distribution.

The number of elements, the inter-element spacing and the spacing method can be specified in the x- and y-direction, respectively. 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. The excitation per element is the product of two linear array excitations, one laid out along the x-axis and the other laid out along the y-axis. It is important to note that the side-lobe specification is not guaranteed, since the layout is not adjusted to achieve these goals.

More information about how the array synthesis tool should be used can be found in the array article in the information browser. This article also describes the different excitation tapers in more detail, and provides references for further research.
