Concentric Circular Array Scan Angle and Gain


This synthesis algorithm will design a concentric circular array (consisting of a set of concentric rings of array elements) for a specified directivity in a given azimuthal and elevation direction. The array is always designed so that the elements are arranged in the x-y plane, centered around the z-axis. When isotropic array elements are assumed, the synthesized radiation pattern of this array will be a mirror-image around the x-y plane.

1 An example of a 3D pattern for this array.

An azimuthal and elevation direction for the main beam may be specified together with the required directivity of the main beam. The angles are as defined below.

1 Azimuthal (Φ) and elevation (θ) angle definition.

The excitation distribution taper may be chosen as uniform (all elements excited uniformly) or based on a Taylor distribution. When using a Taylor distribution, the level of the side-lobes and/or the number of sidelobes to be kept at this level may be chosen, while the Uniform taper provides no sidelobe level control....

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.
