Hi all: I want to know how to plot radiation pattern in dB (Logarithmic) in matlab? Thanks.
hi anybody has matlab code or any program to plot radiation pattern of different types of antennas (dipole,...) both 3d and in the planes xy,yz,xz,... or any other plane thanks
Hi, I want to find an equation which can describe the radiation pattern of an arbritary monopole. I want to use this equation to plot the 3-D radiation pattern in matlab. I also want to investigate the difference in radiation pattern when the monopole (...)
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.
Hi, i am doing a project to simulate the radiation pattern of antenna in matlab. Can i get any code that can help me to plot the radiation pattern in E-plane and H-plane? thanks for help.:-D
Hi there. I'm looking for help on the simulation of loop antenna's radiation pattern on polar plot. I am rather lost. I have read some things on the topic and even browsed through matlab's HELP ... but I couldn't find anything that could teach me how to plot the radiation (...)
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 (...)
Hello, I've made a 2x2 aperture coupled microstrip antenna array. I have the S-params of each antenna element, and also of the corporate feed. I cascaded them in Sonnet with Netlist. The resulting plot is a S11 plot. I'd also like to get the radiation pattern. Do you know how I can get this? I've heard I can (...)
i would like to plot the simulated and measured radiation pattern in polar form. How can i achieve this?
hi i have the same problem is it possible to shre your matlab code? i want to plot farfield result wich i get from cst (i have numbers in db for each theta ) i just use polar (theta,farfield) comment but my 0 position and 90 ,.. arent same as a farfield plot .what should i do?
hi @nsoft desinger draws the radiation pattern in polar plot. how I can convert into rectangular plot ???? Thank you .
plotting polar patterns in matlab could be proved very tricky ;) matlab converts negative numbers to positive/180phase... 2D polar patterns need to be carefully converted before plotting... Moreover, 3D polar patterns are impossible with matlab... You (...)
use the plot3 function but your inputs should be proper.
Can anybody help me to make 3D plot of any type of Antennas' radiation pattern. Help me please for matlab 7.0. Waiting
Try Originlab or Stanford Graphics. They have polar plots...not sure if excel has a polar plot template.
Have u capture the 3D data from measuremetn? You can build a 3D matrics in matlab to plot the 3D graph
hi can any one plzz tell that how to plot the radiation pattern of a parabolic raflector array in matlab.?? does it depends on the no of elements if so then plzz tell how can i calculate the radiation pattern..!!! thanx in advance..
in the book antenna and em modeling with matlab he used sphere for the radiation pattern plot of the antennas ,how to model that spher in matlab
Hi, Is there a quick tool to generate the radiation pattern plot for wire antenna /array Thanks
dear acrislg thanks for your reply I try this code but unfortunately obtain this plot: Phi=(0:1:180)*2*pi/180; Theta=(0:1:180)*2*pi/180; =meshgrid(Theta,Phi); R=sqrt(1-(sin(THETA)^2.*sin(PHI)^2)).*(sin(pi.*cos(THETA))); X=R.*sin(THETA).*cos(PHI); Y=R.*sin(THETA).*sin(PHI); Z=R.*cos(THETA); figure(); me
I want a matlab code for plotting radiation pattern of broadside array antenna and also for endfire array antenna
Who said you cannot with dB values. you have to do a scaling of the dB scale in order to plot.like this i dont have matlab installed on my new puppy ,old one crashed otherwise i would've shown you how.but for time being consider this polar(theta,40-10*log10(x) and fit yours into the above .you do a 40 Db adjustment because log of negative value
Hi radiation pattern give you an idea about the coverage of an antenna gain and maximum detection area (3dB point ) the easiest way to draw the radiation pattern is to draw it manually by direction and magnitude you take the antenna and feed it by power and use an isotropic detector (omnidirectional ) to receive the signal (...)
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
hello to a looking for any matlab codes that plot out the radiation pattern of a circular patch antenna...does anyone know anything in regards to this matter?
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 !!!
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 patterns of azimuth and vertical planes by (...)
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 patterns? Any input will be highly appreciated. Many Thanks, Cross
Hi, I need to calculate pattern radiation. Could someone send me a matlab code to plot the pattern radiation of helicoidal antennas? Thanks!
Hi everyone, I have to plot a 3D plot of a microphone array beampattern 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, am doing my final project at the university of zambia africa. somebody help me with how to simulate or write a matlab code for a 3D plot of a gsm base station antenna electric field strength that is its variation as u move away from the station, that is keeping in mind the type of antennas used. also the code for radiation (...)
Hello Is there a method to plot the radiation efficeincy vs frequency using the transient solver of CST microwave studio ? it exists in the radiation pattern but only vs theta or phi for a single frequency thanks
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.
hello everyone : i have two questions to ask ,may be very simple to most of you 1 i am simulating patch antenna,i can obtain the s parameter of the antenna with different dielectric constant separately , but how to contain the s parameter with different dielectric constant just in a plot for the use of comparation?ia there any effect
