i need help about radiation pattern of monopole antenna plot in cst. In 3D pattern its doughnut shaped , but when choose phi=0 , i not get full circle. my antenna is placed in X-Y Plane. if i choose theta=0 then the complete circle i getting in polar form. should i have to choose theta =0 for radiation plots?
Hello everyone I need your help, I do not know if what I'm doing in cst is right or not! I wish to have E_theta and E_phi radiated by the antenna: Figure 1. I choose E_field or E_pattern? Figure .2. Is this what the E_theta and E_phi ?? Thank you for your help133954133955
Hi everyone, I am currently developing software in MATLAB to calculate the S21 parameter based on the E-farfield pattern simulated in cst. However, MATLAB doesn't calculate the correct S21 values from these farfield patterns. I read something about Antenna Calculation in the cst design studio handbook (p.93). When (...)
Hi Can anybody help me to make plot of phase of Antennas' Radiation pattern in HFSS? in cst Studio software, Farfield results, plot "theta phase" and "phi phase" of realized gain of Antenna pattern. How we can plot phase pf pattern in HFSS like cst? Thanks
Hi all, I am new here but I have been using the forum for many time, thanks to the really helpful community. I am trying to figure out the most suitable antennas placement on a vehicle for V2X applications, in order to get a good coverage in the area around. The working frequency is 5.9Ghz. I already have the antenna model designed on cst, t
Dear all, I have notice that when I represent the radiation pattern sometimes I get a green curve which is not mentioned in the legend of the plot. Can anyone tell me what does it really stand for? I have attached an example which clarifies more the question thanks! 126751
I know that dBi and dBm are different, so I was wondering where I would be able to find the dBm value for my antenna. I only see the dBi value in the farfield plot. Any help would be appreciated.
Hi! I designed a simple (y-oriented) half-wave dipole excited using a discrete port in cst MWS. I had a look at the radiation pattern and it seems just fine as compared to analytical solution. It returns a directivity of 1.6 and E-plane HPBW of 78 degrees. The issue I am having is the radiation pattern in the H-plane shows ripples (...)
For the radiation pattern of antenna, I took polar plot with Phi=0 and theta varying to get E-copolar and phi=90 and theta varying for E-cross(X-pol) polarization. How should I plot H-co-polarization and H- cross polarization from cst results?

Hi every one, I am beginner in cst i need to simulate a enclosure and Find a Shielding effectiveness, can anyone help me to do the same. my frequency range is 3 GHz how to plot a SE in cst or HFSS Thanks in advance
Please read the getting started manual available with cst. You can find the steps to obtain radiation pattern in the documentation. Before you start the simulation you must right click on field monitors and then create new field monitors and select farfield monitors. If you read Antenna Theory by Balanis, you should know what parameters to look in
Dear all, I am designing a simple slot antenna (just a rectangular cut in the ground plane) at 75GHz on a thick Si substrate .

how i can plot e plane and h plane patterns such az attached picture in cst?
I think, in cst, and similar in HFSS, you get to see the radiation patterns using a field monitor. You can select the types of field you want to monitor You can then make the resulting plot options display it as Cartesian or Polar instead of 3D

Anyone can help me for the above? Thanks
Such sources are usualy named 'Radiation pattern Source' or 'Far Field Source'. These are available in EMCoS EMC Studio, FEKO or cst, I am not sure about HFSS. In each tool you can find in documentation format description. Check out this thread with examples:
now i'm designing a dipole antenna with apply the discrete port in between the gap.But the problem is I don't know how to implement it to the hardware part, so is it anybody know when i fabricated it on the PCB,what kind of connector i should use to do the measurement on return loss and radiation pattern.
