How to make antenna gain and phase plots?

Many antenna-related papers and dissertaions feature plots that look like the attached. How do people make them? What function is used?

This is a polar surface plot with a colorbar. Did you search for those terms already? There is a very good chance it is already implemented in Matlab or that it exists on the file exchange.

I found several plotting functions, including polarscatter. Is that a possible way to make this plot? You'd probably have to turn the angular axis off.

Hi @Krutant Mehta,

As per my understanding, you would like to know how to plot Antenna Gain and Phase plots in MATLAB. MATLAB provides comprehensive support for antenna analysis and simulation through its "Antenna Toolbox".

Utilize MATLAB's "pattern" and "patternCustom" functions to plot radiation patterns and phases of antennas. Refer to the following MathWork's documentation for more information on these functions:

• https://www.mathworks.com/help/antenna/ref/cavity.pattern.html
• https://www.mathworks.com/help/antenna/ref/patterncustom.html

Refer to this example on Antenna Modelling and Analysis and learn more on modelling an antenna, modifying it's properties and the using the "pattern" function:

You can also refer to this MATLAB Answer which provides more links related to plotting antenna gains and phase plots:

I hope this is beneficial!
