Phased Array Gallery
This example shows how to model and visualize a variety of antenna array geometries with Phased Array System Toolbox™. These geometries can also be used to model other kind of arrays, such hydrophone arrays and microphone arrays. You can view code for each plot, and use it in your own project.
Linear Arrays
Linear antenna arrays can have uniform or nonuniform spacing between elements. This most common linear antenna array is the Uniform Linear Array (ULA).
A Minimum Redundancy Linear Array (MRLA) is an example of nonuniformly spaced linear array. The MRLA minimizes the number of element pairs that have the same spatial correlation lag. It is possible to design a 4-element array whose aperture is equivalent to 7-element ULA.
Circular Arrays
Circular antenna arrays can also have uniform or nonuniform spacing between elements. Next is an example of a Uniform Circular Array (UCA).
Multiple circular antenna arrays with the same number of elements and different radii form a concentric circular array.
Planar Arrays with Rectangular Grid
Planar antenna arrays can have a uniform grid (or lattice) and different boundary shapes. Next is an example of a Uniform Rectangular Array (URA) with a rectangular grid and rectangular boundary.
You can also model a planar antenna array with a circular boundary. The following code starts with a URA and removes elements outside a circle.
Next is an example of a planar antenna array with an elliptical boundary.
The next example is a hexagonal array with a rectangular grid.
Planar Arrays with Triangular Grid
Triangular grids provide an efficient spatial sampling and are widely used in practice. Here again, different boundary geometries can be applied. First is a rectangular array with a triangular lattice.
Next is a circular planar antenna array with a triangular lattice.
Next is an elliptical planar antenna array with a triangular lattice.
Next is an example of a Uniform Hexagonal Array (UHA).
Thinned Arrays
You can also model planar antenna arrays with nonuniform grids. Next is an example of a thinned antenna array.
Hemispherical Conformal Arrays
You can also model nonplanar arrays. In many applications, sensors must conform to the shape of the curved surface they are mounted on. Next is an example of an antenna array whose elements are uniformly distributed on a hemisphere.
Subarrays
You can model and visualize subarrays. Next is an example of contiguous subarrays.
You can lay out subarrays on a nonuniform grid. The next example models the failure of a T/R module for one subarray.
Subarrays can be interlaced and overlapped to mitigate grating lobes.
In certain space-constrained applications, such as on satellites, multiple antenna arrays must share the same space. Groups of elements are interleaved, interlaced or interspersed. The next example models interleaved, non-overlapped subarrays.
Another type of nonplanar antenna array is an array with multiple planar faces. The next example shows uniform hexagonal arrays arranged as subarrays on a sphere.
You can also view the array from a different angle and interactively rotate it in 3-D.
