doubt is why we want to measure the radiation pattern while simulating the antenna in hfss,and what is the purpose of measuring vswr in antenna design ,is there is any coorelation between the vswr and return loss. 2.correlate the vswr,radiation pattern definition in detail with hfss (...)
The directivity diagram dosen't look right. As it is symmetrical you should have the same radion pattern in H and V. It looks like it's basically is just a wrinkled up cross dipole, if so it should have the same radiation pattern as a dipole.
How to make this UWB patch antenna better Hello Sir/Madam... Kindly see the attached picture. I have made a patch antenna. What I need I want to know how to make it better so that its radiation pattern will become uniform through out the bandwidth almost circular pattern. I want to also make its S11 (...)
The calculation probably shows the area at the foot of a cone where the transmitting antenna is the peak and the angle is known from the antenna radiation pattern. That doesn't necessarily change with gain although there would be some relationship between them. The gain might detemine the strength within the footprint but (...)
Hi all.. after simulating my antenna in IE3D, i fabricate it and measured using VNA, In my results they are given me gain vs frequency value in excel sheet, i just want to know how to plot Axial ration bandiwdth plot using that reading.. plz reply
135715135716 Hello Can anyone explain me why the radiation pattern look like this for a dipole antenna on flat substrate. It is very wide and asymmetric to theta = 0 degree. Thanks
in order to measure the radiation pattern of an antenna both the antenna should be of same polarization. 1. how to determine the polarization of the antenna. can you tell by looking at an antenna. 2. if in datasheet it's written only linear then which type of polarization it is (...)
Hello every one, I'm a student, i have designed a PIFA antenna with coaxial work correctly but the problem when i want to design the airBox for radiation pattern i have a bad result.i have tried to put the length of the box lambda/4 but i have the same problem. Please it's urgent any body can help me to configure my box and thanks
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 (...)
can anybody please explain the radiation pattern of seawater antenna to me for my further researching?
Hello guys! I'm simulating a CPW fed on-chip monopole. But the right radiation pattern couldn?t be obtained at 79GHz even when the length of antenna is changed from 0.2mm to 0.9mm. But I could get a good radiation pattern at around 50 to 60GHz whatever the antenna?s length is. 135036 (...)
how to calculate the minimum separation between body and wearable antennas. if it's very small the absorption because of body will be high and and also it effects the input impedance and the radiation pattern of the antenna. one good approximation is to be keep the distance of (2d2/lambda) from the body for which results (...)

hi , I have a problem that when I make a dipole antenna parallel to the PMC the radiation pattern is wrong so can someone help me with the steps or something like that ?!
I assume this is a resonant patch-like antenna. For the S11, do you know why there is a point with low S11 around 7.25? It's probably some other resonant mode of the antenna. Have you investigate the radiation patterns/current patterns? And for the gain pattern created for 5.8 GHz why there i
I did not understand your first question. Yes, HFSS computes fields on the outer radiation boundary and then it calculates the Far-field radiation pattern from the calculated field quantities (on radiation boundary)
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
I have attached the radiation pattern of my design simulated in HFSS.what is inffered from this pattern.how shall i explain my pattern to others.
I'm looking for a polar plotting routine/app. I need to plot the radiation pattern of an antenna and only have a rectilinear plot capabilities. Input data to the plotter will be via a data file.
A basic question regarding the interpretation of measured antenna radiation pattern data. Usually the measured antenna radiation pattern data includes the Phi , Theta angles and Ephi_amplitude, Etheta_amplitude and their corresponding phases for each Phi and Theta angles. When refer to (...)
