To make it an antenna, we need to add a voltage source to the center of the wire. WinProp Highly accurate and very fast wave propagation and radio network planning software Learn More.

In addition, it cadteko calculate the isolation or mutual coupling S12 between pairs of antennas, the near fields around an antenna and the electric currents that flow on an antenna or the surrounding structure. We immediately see a graph of the 3d Radiation pattern. You can change these parameters if you would like. Note that the gain is 0. Now we need to mesh our geometry our geometry is just the wire.

The default setting will be the entire sphere, with a grid sampling in 5 degree increments. We need to specify a port impedance.

Then click create, and the variable is saved in the Variables Tree.

The Request Far Fields window pops up, and if you click the 3d Pattern at the bottom, you will be requesting the far field pattern. The frequency window pops up, and Enter e6 for MHz, then click ok: You can also rotate the radiation pattern in 3d if you want by clicking on the graph and moving it around.

Click Create, then Close. This will determine the required lengths for you based on the frequency we specified.

It is simply a wire the default property all cadfeio created is to be cadfdko of metal with infinite conductivity — which is usually what you want.

The mesh needs lengths specified, which will determine how finely to grid the geometry. Be The First To Know Subscribe Altair and our resellers need the contact information you provide to us to contact you about our products and services.

If the wire is to be thicker, consider using a cylinder instead to model the antenna.

For wire segment radius, this should be significantly smaller than the segment length — we want the wire to be thin. We need to specify the solution frequency now. This is all the geometry we’ll need to model a simple wire antenna.

A create line window pops up. The easiest way to learn this stuff is to play around with it. Comprehensive Electromagnetic Software Watch this quick introduction video to learn how Feko can help you. If you click directivity, you will get 2.

You may unsubscribe from these communications at anytime. You can assign a name here if you want, but VoltageSource1 the default is fine.

We can also request currents if we want, or S-parameters. Altair and our resellers need the contact information you provide to us to contact you about our products and services.

We now have a port, but to calculate the radiation pattern we will need to apply a source. To view the S-parameters or Impedance of this antenna, simply click the buttons on the top row, and then play around with the display settings. Continuing the FEKO tutorial from the previous page, we now have a line that represents our dipole antenna. The add voltage source dialogue pops up. Click create to create the dipole, then close to close the create line window. The following window pops up, and we enter the length as 0.
