Hello, I need some help in design a directional coupler, I got the results in MWO but they does not match in hfss, any one know or have a file about special condition to design Directional coupler coupled line in hfss please help and I know to see the even (...)
Remember the following points 1. The conventional Wilkinson power divider is a narrow band device. So fix your frequency band of operation and try to optimize within those constraints. It would not be fruitful to try for anything over 20% (...)
hi forks, does anybody know how to simulate balanced filter using hfss 12, i.e. how to excite the even mode and the odd mode? Thanks in advances.:roll:
Hello, I'm currently designing a Patterned (w/ Slots) Marchand Balun to increase the even/odd Impedance Ratio for good balance. LineCalc is able to simulate Zoe and Zoo given the width and spacing of a (...)
hi i m simulating a waveguide structure as a coupler. its a four port structure. i need to calculate even and odd mode propagation constant. i have used driven modal solution but it cannot calculate even odd mode beta. i have seen in some (...)
I'm using hfss for a specific coupled CPW line simulation. Driven modal are used. Two waveports are places at both ends of the coupled CPW line and two modes (even mode and odd mode) are (...)
Seems the hfss 11 or 12 has some changes in result report. In hfss 10 or ealier version, I see the method to extract the even and odd mode impedances of couple-line as follows in the previous post. (1) Choosing the driven terminal (not driven modal); (...)
Hello, friends. I would like to design a direction coupler at a center frequency of 2.6 GHz. I prefer to simulate the strukture in the hfss software. But i am not clear with the definition of the even and odd mode port definition. Can anyone give me some suggestions (...)
(1) Choosing the driven terminal (not driven modal); (2) draw two terminal lines when setting the waveports; (3) after simulation, you can get the differential impedance Zdiff and common impedance Zcomm. Then the even mode impedance Zeven = 2*Zcomm, the odd (...)
Dear all, I have simulated a differential pair lines (GSSG). I selected driven-modal solution for a number of modes of 2. From the E-field pattern, it is clear that mode 1 is even mode, mode 2 is odd mode. Question: The Zo in the matrix data: Zo mode (...)
Hi, everyone. I have a question about the differential pair definition in hfss Driven Terminal simulation. I am wondering is the Differential Terminal Port Impedance equal to the odd impedance and the common terminal port impedance equal to the even mode impedance in the (...)
The integration line is the line where the E-field is integrated for obtaining Voltage. It decides the direction of E-field. For two-conductor system, the ingetration line should be from one conductor to another for odd-mode excitation and from conductor to ground for (...)
Hi all, I have been recently trying to simulate a pair of coupled striplines in hfss. I tried but failed to obtain the coupled lines' characteristic impedance and relative dielectric constant for even-mode (Zoe, Epsilon-re)and (...)
Hi all, I have been recently trying to simulate a pair of coupled striplines in hfss. I tried but failed to obtain the coupled lines' characteristic impedance and relative dielectric constant for even-mode (Zoe, Epsilon-re)and (...)
HI, folks: I've start running hfss on diff trace. There is only two metal traces in the model. I used driven modal analysis. Two modes are calculated by solver. mode1 is odd-mode and mode2 is (...)
When you assign a waveport which includes two or more conductors, you can pair them for even-odd mode excitation. I would recommend you to get some examples and slides from Ansoft homepage and try them first.
