Hi The problem appears because port Z0 is 50 but antennas have different Z , so there is poor impedance matching.
Hello everyone, As I'm working with modeling of the transducer array (Murata MA40S4) by using matlab. The matlab Phased array toolbox offer me two kinds of elements (antenna and Microphones) with various kinds such as isotropic, cosine, custom.... Here are my questions: Is this toolbox helpful for (...)
my professor wanted me to design 2x2 antenna array which gives a pattern similar to cardioid but it has to be 1 everywhere except a narrow notch point. i have been trying 2 weeks around 2000 combination but i still can't find it. my matlab code is : clear all f = 1e6; c = 3e8; lamd = c/f; k = 2*pi/l
hi there, first post here so hello. I recently started using cst. I'd like to know if and how (i believe it is possible since it is possible on software such as HFSS & FEKO) to import antenna parameters from matlab to cst automatically. I have a matlab file which produces parameters for antenna arrays (...)
Hi Guys I am trying to represent array factor using phasor representation in matlab (ref Balanis) Can anybody suggest me how to represent contribution of each element of antenna array in phasor form using matlab I want each phasor to start from end point of previous phasor, where each (...)

Hi guys, My project is adaptive beamforming using LMS algorithm I've applied this algorithm on 8 element array antenna and 8x8 rectangular array antenna correctly, right now, I want to show the effect of applying this algorithm in channel capacity, power consumption, frequency reuse or distance of transmission. anybody (...)
Hi all, I have some simulations of 3D structures, which are composed of an antenna array (conical array in fact). That I want to do is to use the radiation pattern of each element in a matlab code, and do the all array pattern reconstruction. I already use the 3D antenna (...)
as i am not much good in antenna theory, can you give me reference of the exact equations i have a 2x2 array of yagi udda antennas thanks
You can easily export the data simulated by CST such as antenna patterns in the ASCII format to use in matlab. however CST can be used for the antenna array analysis perfectly and you do not need matlab.
Is it possible to compute and analyse mutual coupling of a phase array antenna in matlab? Any method to do that? I'm not able to determine how to proceed. I have read and understood the concepts from Balanis and Kraus, to implement it in matlab, im finding it difficult. I chose to do this for my college project, and now in (...)
i need your help ... a need any book , handbook , thesis in calibration methods object . if you have any matlab program to music algorithm for direction finding or matlab program for any method of array calibration pleas help me as soon as possible
Far field is a function of angular coordinates teta, phi. Therefore, Far field=E(teta, phi), normalized Far field=E(teta, phi)/Emax. Far field of dipole f angular coordinate phi =1 %Far field of dipole f angular coordinate teta t=-90:0.01:90; E=cos(t*pi/180); plot (t,E,'k'); grid on; %Far field of antenna array t=-90:0.01:90; % teta

Hi, i am doing a project on yagi antenna and would like to know the formula for calculating azimuth,elevation and array factor as these are needed from what ive read to draw the radiation pattern. i hav chosen a freq of about 900MHz and i am starting with a 6 element yagi. I would also like to obtain matlab code for dra
want to see a plot for isotropic point source antenna array but not getting the right output. can anybody tell me where i am doing the mistake. n=4; // no. of point sources k=2; //(for distance between adjacent sources; d=lambda/k) delta=0;
is there any matlab codes available to analyse the stub of a cts using fdtd method
Check the CD that comes with Balanis text book antenna has all the matlab simulations of the most figures and programs in the text book Best regards S.Mohammed.
Hello everyone, Does anyone know how to create variable arrays in FEKO? For the life of me I can't figure it out or find any documentation. The application is to create a single array of lengths for a Yagi antenna. that way, when I want to tune the lengths, I can address the entire array (like in (...)
For what kind of array antenna, linear, planar or circular? ---------- Post added at 07:41 ---------- Previous post was at 07:37 ---------- For what kind of array antenna, linear, planar or circular? In case of linear array with m-elements, u can try this AF=exp(-j*(2*pi/l
hi...i am doing the an undergraduate dissertation on "Optimum design of smart antenna array", can anyone please give me an idea about it and tell me how should i start it and what should i read first to be able to understand it. i have to implement it in matlab. i would appreciate your responds. kind regards
Hello everyone ... A few years back, I designed a matlab based toolbox for phased array antenna analysis and design ... Due to some reasons, now I am planning to re-implement this code in Python ... I would like to know if anyone is interested in this kind of work ... You can see some screen shots of my matlab tool (...)
It depends on what kind of beamforming networks you are using. Butler matrix? Rotman lens? Added after 1 minutes: By the way, there are available matlab code for antenna array. You can find them from Balanis' book.
Hi, Is there a quick tool to generate the radiation pattern plot for wire antenna /array Thanks
Hello everyone, I would like to know if there's a software/matlab code I could use in order to convert the pattern of an antenna element to a formula that can be plotted in matlab. For example : % element pattern of dipole antenna g(theta) = abs((cos(pi*cos(deg2rad(theta))/2))/sin(deg2rad(theta))); How is (...)
Hi folks, I am working on a thesis topic regarding time modulated frequency diverse array radar. I am trying to simulate this antenna using matlab. It will basically excite the elements in a periodic manner one at a time along the array axis and apply a frequency offset for each element, as well. Does anybody have any (...)

Hi, everyone. I have a basic question about using matlab program to calculate the antenna directivity by using the field data. The field data are stored in a N-by-M array of magnitude of the E field, N is the phi angle from 0 degree to 360 degree and M is the theta angle from 0 degree to 180 degree. My calculation is basically (...)

hi, i need matlab code for genetic algorithm which is used to design an array of antenna will u help me thanks
strange to compare a 3d tool to a more or less programming approach - CST should also be included since it has time and frequency domain solvers - it can cover a broad range of antenna types....
I need matlab code for adaptive beamforming for OFDM- antenna array systems. Your help will be beneficial for me.. Best regards
Look at the book "antenna and EM Modelling with matlab" ( ), there you have explained elementary theory and implementation about.
which antenna element do you used? why do you simulate in matlab?
