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

cn we able 2 find out the directivity in 2d **plot** of half wave dipole,....i got 8 shaped **radiation** **pattern** hw 2 obseve its directivity?? i hve given theta range from 0:pi*0.01:2*pi,.and electric field formula e=(cos((pi/2)*cos(theta)))/sin(theta) ,.i am doing in **matlab**

you can use polar **plot** available in excel/**matlab** or if your simulation software imports txt file you can use that too!

Why would you want to simulate an antenna when you already have the **pattern**?
Knowing the close formula, i would use **matlab** to **plot** the **pattern**.

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.

Hello,
Yes, you can do it by using **matlab**,I've tried and I think that it works. 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 everyone, I have to **plot** a 3D **plot** of a microphone array beam**pattern** using **matlab**.
For example, I have to **plot** the 3D **pattern** **radiation** of a microphone array with M=7 microphones, with d=0.05m element spacing and uniform shading.
I think I have to use the function surf. (...)

Hi to all,
Can anyone provide some input how one can **plot**/generate in **matlab** and/or C# (or C++) a 3D antenna **pattern** from the E and H plane **pattern**s?
Any input will be highly appreciated.
Many Thanks, Cross

hi friends
can u tell me how i can get gain in dB,beamwidth and directivity of a **radiation** **pattern**. I am using HFSS,it gives very large values because it does not consider reflected powers.
I want to **plot** it on **matlab**. i get **radiation** **pattern**s of azimuth and vertical planes by (...)

Try Originlab or Stanford Graphics. They have polar **plot**s...not sure if excel has a polar **plot** template.

hi guys !!
how can i integrate this function in **matlab** ? E=(cos(2×pi×cos(θ)) - 1) /sin(θ)
also , how can i **plot** the (RP) **radiation** **pattern** of an antenna in 3D ...
where ; RP = =((cos(2×pi×cos(θ)) - 1) /sin(θ))^2
thank u !!!
