How can I draw "Omnidirectional Antenna Diagram" like this image?

How can I draw this diagram on MATLAB? ( U = |sin^n(theta)| )

Hello Furkan,

You can plot omnidirectional antenna patterns using MATLAB’s “pattern” function. You would need the Antenna Toolbox to use this function. Below is the example of the code that plots the radiation pattern for a dipole antenna at a frequency of 70MHz and the resultant plot

d = dipole; 
pattern(d,70e6);

Please refer to the following documents for more information
