15 Threads found on edaboard.com: Cross Dipole Antenna
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.

I think no antenna can be designed to optimally radiate both LHCP AND RHCP , only one way is possible.
To assist the pretty clear explanation, no antenna can radiate it simultaneously. But a suitable antenna e.g. a cross dipole can generate any polarization with respective phase shift and magnitude of the (...)

Q6. The excitation is placed to along the edge of the mesh, so when two ports cross each other, they have electrical connection, which is not the kinda feed we are interested.
Q7. You may try something like the given in the attached simple dipole model. You will still keep the original phase difference. To be even safer, make sure that those feed

Which one is co-pol and which one is cross-pol? It is determined by the user. If you consider E-theta on the constant Phi-plane is the co-pol, then the E-phi on the constant Phi Plane is cross-pol.
E-plane is where the E-field is lying on. It is easy to figure it out for simple antennas such as a (...)

Hello Every one,
This is Shaista from Islamabad.I want to do thesis in the field of antenna designing. I have done my Project on 4 cross 4 matrix strip antenna. I want to take it futher for my MS thesis. If any one suggest me any kind of improvement or any book related to antenna designing that help me choosing my thesis. (...)

i have faced a problem in building the geometry of a log-periodic dipole array in IE3D. i could not rotate the antenna boom(of rectangular cross section or may be cylindrical also) along its own axis (boom's axis),so that the elements that r in (+z )direction will be oriented in (-z) direction after the desired operation.

Some X-polarization base station antennas have dipole-pairs in two configurations:
1) in X (cross-shaped) providing 90deg HPBW in horizontal plane
2) in <> (rhombic) providing 65dge HPBW...

To simulate LPDA, this is same with yagi antenna (non folded),
But all element is driven and is connected by transmission link with cross link connection.
The transmission line have impedance can build with two parallel boom.

hi, i am trying to visualise a linearly polarised antenna in the E-plane cut in HFSS. say for example a dipole in the z-axis.
If i use E(theta) to plot the E-plane pattern, would I get a co-polarised plot?
and if i use E(phi) to plot the E-plane pattern and get a cross-polarised plot?
and if I use a horn to measure the pattern in the (...)
