design a pyramidal horn antenna with cst 2010

Hi everybody,

I'm new here. I want to know how to design a pyramidal horn antenna using CST 2010. I've read the help funktion, but they just describe a conical horn antenna. Thanks for the help

Here is an examples of how you create components in CST: All Applications

So you want to design a pyramidal Horn.

Start by defining what kind of horn. Frequency, bandwidth, feed etc. The desired electrical characteristics are important too. Yogi has a quote that went something like this: If you don't know where you are going you won't know when you get there. Figure out where you want to go. (It is your specification so feel free to modify it if you need.)

A good starting place for pyramidal horn design is Kraus. Some like Balanis as an alternate. Microwave Journal published a series of tables years ago that are useful as well.

Once you have the above worked out you are ready to tackle the simulation using one of the many tools available. CST is just one of the choices.

As a very general statement, pyramidal horn antenna are usually in the range of gains from around 10 dBi to about 20 to 25 dBi gain. Any higher and they get too big. Polarization is typically linear and bandwidth is that of a standard rectangular waveguide. E and H plane pattens are usually different with the E plane sidelobes generally elevated relative to the H plane. A good place to get an idea of horn performance and size is to review a set of "standard gain horns" offered commercially from a variety of sources.

Hello, to design such an antenna, try to use 'Antenna Magus' software if you have acces on it. It can be helpful to design pyramidal horns and then to export the design in CST mask to simulate it in CST; You will have also all the parameters defined on CST so you can do optimizations also.
