--> This program module allows the simulation of the radiation pattern produced by a linear array having uniform amplitude and phase.
 

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

• if you choose uniform, the distance among the array antennas will be the same. In this case, you have to specify the antennas spacing (i.e., the distance between two adjacent antennas). 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 the z-axis, specifying its position in the input field Z.

• The number of antennas along Z 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 linear 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.
