Hello everyone,
This was haunting me quite some time. I really want to know how to calculate the **characteristic** **impedance** of a suspended stripline. I know there are some tools that can calculate all the parameters like Zo, physical length, width, etc but there's none for suspended stripline.
Let say i have this values:
frequency 2GHz

The line **impedance** (**characteristic** **impedance**) of a uniform transmission line, is the ratio of the amplitudes of a single pair of voltage and current waves propagating along the line in the absence of reflections.
The wave **impedance** of an electromagnetic wave is the ratio of the transverse components of the electric and (...)

It sounds like **hfss** is still normalizing to 50 ohms, even though the **characteristic** **impedance** is no longer 50. When you first make your lumped ports, you have an option to check a box "normalize all modes" or something to that effect. Maybe try unchecking that and normalizing on your own? I would think that **hfss** would (...)

Dear all,
as I am having some trouble with my antenna design, I started splitting it up in small problems:
My very first problem is about designing a slot line and determining it's **characteristic** **impedance** Z_0.
My simulation is quite easy:
I have defined a slot line on a low dielectric (epsilon_r=3.5) substrate (h=251?m). The slot line w

Hi,
I am a newbie to EM simulation / **hfss**.
I used the lumped port (2 port modelling of transmission line ) initially to calculate the S parameters of the transmission line in **hfss**.
Then I realized that I need to use the waveport to find the **characteristic** **impedance**. I made slight modifications in the dimensions of the (...)

Hi STINGERX,
The width of each strip is governed by its **characteristic** **impedance**, whereas the length is dictated by the required phase shift. As such, There are only 2 unique elements.
Good Luck

Hi,
Always use wave ports for microstrip line. And the integration line for microstrip line must be in between the substrate with Zpv as the **characteristic** **impedance**.

I hope this is the S-parameter you need, right? If you can send me your e-mail address, I will send you the .**hfss** file.
You say your S21 is

Hi all,
Based on the generalized S parameters used in **hfss**, is it correct that, when simulating a microstrip line for example:
1) The **characteristic** **impedance** of the line is found by NOT re-normalizing the port and the **characteristic** **impedance** of the line is equal to the wave port (...)

According to the transmission line theory, the **characteristic** **impedance** of the device Zo, propagation constant γ only should be related to the materials and the cross-sectional structure theoretically. And **hfss** solve the 2D fields first, then solve 3D fields. For this, I want to ask three questions:
1 Choose ?solve ports only?, (...)

Hi all,
I have been given a task to draw a structure of Coplanar Waveguide with the specification that the center conductor should be of 60microns, the ground planes should be finite and in between two to three times the width of the center Conductor. The substrate could be any silicon or GaAs. I have to adjust the gap width such that in order t

I do not know your simulation but waveguides other than coaxial have other **characteristic** **impedance** than 50 Ohms. If you insert a coaxial-to-waveguide transition, the problem is solved in real situation.

Hello,
When E-field lines generated by your structure cut your dielectric, properties will change. Increasing relative epsilon will reduce the propagation speed in transmission lines that share the higher relative epsilon. **characteristic** **impedance** of transmission lines reduces, cutoff frequency for wave guides reduces, etc.
Even microstrip

Dear All
I am sure this thing has been discussed many times and after reading a number of posts with confusing comments i am writing this for our help. Please correct me if i am wrong any where.
Let me first define the port Zo, this variable is related to the **characteristic**s **impedance** of the port or precisely the **characteristic** (...)

Refer to the site
it gives the **impedance** of strip line
and search for strip line **impedance** you will get the online calculators.
i hope it helps.good luck

What's the meaning of the Zo in **hfss**? Is it **characteristic** **impedance**? If so, what is wrong with this **hfss** model? The Zo of the grounded CPWG (Co-Planar Waveguide) is varying a bit obvious with the frequency while the Zo of the microstrip is not. According to the Lincalc tool in ADS, both the **impedance** (...)

Dear all,
I've previously started (and closed) a thread in this forum (06-04-11) about the **characteristic** **impedance** calculation of rectangular waveguide in **hfss**.
The conclusion at that time was that the results given by **hfss** were not in accordance with the classical electromagnetic bo

Hello,
The **characteristic** **impedance** is badly implemented in **hfss** to my opinion: the only way to find the same value of the analytic **characteristic** **impedance** of the TE10 mode is to define an integration line and set the **impedance** calculation to Zpv. Then, you will find the same analytic (...)

When you are defining waveports, renormalize the **impedance** of the waveport. So the **impedance** is equal to the **characteristic** **impedance** of 50 ohm.

Hello,
I am implementing Power divider using stripline. I have used lambda/4 = 75mm (1GHz) & air as a dielctric material. My question is that suppose i want to implement 57ohm line so to find out width ill first terminate it at 57ohm then see the reflected **impedance** if both are same then it is 57ohm **characteristic** line. Now if i terminate this l

Dear all,
I'm puzzled by the result given by **hfss** (v12 or v13) in a simple rectangular waveguide case.
When modelling a rectangular waveguide which cross-section dimensions are 72mm x 34 mm (WR284) and let say a 200mm length, at 3GHz, **hfss** solution data Z0 are :
- using Zpi (default) integration line : Z0=304.7 Ohm
- using Zpv integration
