Hi,
Transmission lines are an important part in microwave frequency transmission. In terms of waveguides, it is itself a form of transmission line and functions at extremely high frequencies.
Hi,
You can check by calculating port modes only to check the impedance. You can also check the return loss and if the value is at least below -10dB at your desired frequency, then the antenna is matched.
Hi,
It will not be easy because if you want to optimize it in terms of dimension, you will need to change the original solid which you apply the command extrude. I suggest that you design your patch separately for easier optimization.
Hi Hassan_
I don't mean to interrupt but the gain of the single patch can be improved if you used a less lossy material as a substrate compared to FR-4. FR-4 is a high lossy material. If your antenna is meant for long range, than you need a higher gain.
If you look at the top of the CST interface, there is a section called "Mesh" in between the objects and solve.
If you click on it, you will see 3 types of of orientation which is x plane, y plane and z plane. However I have not tried using this before.
I would like to ask that when you...
hi,are you know that useful in underwater for demagnetize submarine or not?

according to the link posted by tpetar, the vessel is placed inside a special enclosure to avoid from interfering with the Earth's magnetic field. So the submarines are placed here as well for the...
Hi,
I got it from wiki. Its called the Deperming process. It says that very heavy copper cables are wrapped around the structure and current as high as 4000 amps are injected to the cables therefore resetting the magnetic levels as suited to the environment. The process needs to be repeated...
Hi,
the cost and also the flexibility in terms of fabrication both favours the FR-4. However there some advantages using hybrid of PTFE/FR-4 (multi-layer) as I found out in this link
