Hi
I am simulating a triangular array using floquet port. as was mentioned in the following post:
https://www.edaboard.com/threads/how-to-using-master-slaver-b-c-to-model-triangular-array.142726/post-615474
I defined three coupled lattice pairs using ansys electronics 2022. the problem is I...
I used copper for conductors and other properties are those mentioned in the book. maybe the results shown in the book are for a slightly different structure. I'll try to set all losses to zero and see what will happen.

those results are fine. As you make the gap smaller...
Hi niki
thanks for the advice about the resonators to be weakly coupled. I changed the feed positions and I got the two resonant peaks:
regarding the book you mentioned: I had seen this book and actually I was trying to obtain the same result which you showed here (figure 8.16). I used the...
hi BigBoss
I want to redesign the results obtained by this paper:
and I used the dimensions mentioned in the paper. this papers mentions 4 coupling coefficients between identical resonators which are placed in different directions and spacing with respect to each other. I am trying to...
hi
i want to find the coupling coefficient of two hairpin resonators with this configuration:
but I'm not getting two resonant peaks to calculate the coupling coefficient:
i don't know what's wrong. are the feeds placed correctly?
thanks
thanks for replying
I found it ! :)
The limitation on the width comes from the excitation of higher order modes (as was mentioned in the attached file). the formula for the cutoff frequency of the first higher-order mode:
increasing the width of the strip, lowers the spurious-free...
regarding my first question above:
there is some explanation in the attached file on how to choose Z0L and Z0C, and it has explained that the value of impedance and width of microstrip line should be determined simultaneously, so we choose a value for the impedance first. but the point is that...
Hi
book title: Microstrip Filtersfor RF/Microwave Applications, by JIA-SHENG HONG M. J. LANCASTER
In chapter 5 of the book, the design of Stepped-Impedance, L-C Ladder Type Lowpass Filter is described. A third degree lowpass prototype with Chebyshev response is chosen and LC parameters are...
