hi everybody,
can anybody expalin how to make 3D polar **radiation** **pattern** in **matlab**?
I am using UV **plot** where with mesh(x,y,z) command
x=sin(theta)cos(phi)
y=sin(theta)sin(phi)
ans
z=calculated gain
all are NxN square matrix
But I want to **plot** in polar form
Thanks

You should check the **matlab** command you used for **plot**. The color usually is according to the Z value by default, rather the distance from the origin as you expect.

Given the RAR compression utility is proprietary, with a closed algorithm, I am not a fan of it, and so don't use it. Yes, I know I can get a free decompressor, but I object in principle to the use of .rar files. There are plenty of good free alternatives, so why pay to compress your data?

If I understood well you want to **plot** your E-field or H-field or Gain (it is the same) as a function of phi and theta. you just have to **plot** A=f(theta,phi) what I suggest is to tranform your funtion in xyz coordinate system and then **plot** A as (...)

Hi hoke!
It is so simple. There are two basic way to do it.
1) If you know the analytic formula you may use "polar" instruction to **plot** the **pattern** in polar coordinate. Of course you have to change the Electric or Magnetic Components into Polar coordinate.
2) If you don't have any analytic formula you may use different numeric methods like

First off all, no need to change the default infinite sphere settings. **plot** a full 3D **pattern** so you know what to expect from 2D **pattern**s. May be you get the same **plot** because the **pattern** is symmetrical.
To **plot** a single plane choose a phi value and sweep the theta values.
