Plotting Radiation Pattern in Fresnel Region(near field) using MATLAB

Hello,

In the antenna tools box, when we plot radiation pattern, is it a far field plot or a near field plot?

Is there a command to plot the near field(fresnel region) plot in matlab?

Thanks,

Hi Biplob,

As per my understanding, you want to plot the near field (Fresnel region) pattern in MATLAB.

When you plot the radiation pattern using the "pattern" function, it plots the far-field radiation pattern of the antenna.

To plot the near-field radiation pattern, you can use the "patternCustom" function in the Antenna Toolbox. This function allows the user to specify the distance from the antenna.

For more information on "patternCustom" function, you can refer to the following documentation:

Thank You Bhanu.

Your suggestions are valuable. I will try this "patternCustom" function and let you know about it.
