hello..
I want to design a 4x4 butler matrix. As we know, butler matrix is consisted of hybrid, phase shifter, and crossover (CMIIW). So i must design each of them properly to make a butler matrix.
I am designing hybrid coupler 90 degree in ansoft hfss now. I am newbie in ansoft simulation..so i can't read well the results.
Work frequency is ranging from 2.35 GHz to 2.44 GHz. The I get the center frequency is 2,3945 GHz. Using copper for the patch and ground plane in 0.035mm, duroid 5880 for the substrate with 1.6mm.
I put my work in attachment..feel free to take a look
Here is some VSWR results..
How to optimize my design in ansoft? :-?
And the last question.. as we know hybrid can shift the phase of the outputs. Output in port-3 is 90 deg from the port-2. How to analyze that?? How to read the phase-shift in ansoft?
Please correct my design if needed.. I'm just newbie in ansoft simulation
So many thanks to you all... :grin:
