--> This program module allows the simulation of the radiation pattern produced by a planar array having arbitrary amplitude and spacing.
 

The Planar array parameters panel allows us to select a uniform or a nonuniform spacing

• if you choose uniform, the array antennas will be located on an XY Cartesian grid. In this case, you have to specify the antennas spacing along X and Y. This spacing has to be specified in terms of a fraction of the free-space wavelength.
• if you choose nonuniform, each antenna can be moved along both the x- and y-axes, specifying its position in the input fields X and Y.

• if you choose a linear phase, the phase varies linearly among the array antennas; in this case you have to specify the alpha phase increment. You can indicate this phase increment both in degree or radian.
• if you choose an arbitrary phase, you can assign to each antenna of the array the desired phase by using the input field excitation (deg. or rad.).
• if you choose a uniform amplitude, the amplitude of each antenna is set to 1.
• if you choose a non-uniform amplitude, you can assign the desired amplitude to each antenna of the array by using the input field excitation .

• The number of antennas along X and Y can be modified by both inserting its value directly and increasing or decreasing it by using the + or - keys.
• The type of antennas can be chosen among: isotropic, Hertzian dipole, half-wavelength dipole, cos^n distribution dipole (in the last case, you can specify the order n).

The Radiation pattern panel shows the 2D or the 3D radiation pattern of the specified planar array:

• In 2D, you can show the radiation pattern in the XY, YZ and XZ plane.
• In 3D, you can click on the pattern and change the view of the radiation pattern using your mouse.
