I have made a Rotman lens with 8 input and 8 output ,4 dummy port for 27 GHz in Ansys designer. but Its phase angle is not correct like its values for ang_deg(4,9)=-90.44, ang_deg(4,10)=134.35,ang_deg (4,11) 176.19, ang_deg(4,12)-=148.90, ang_deg(4,13)=125.45, (4,14)=115.26, ang_deg(4,15)=104.35, ang_deg(4,16)=105.3
this value is for alpha=30, F= 6 (on axis focal length)
I used a matlab code found in internet which is attached here. But I tried to decrease alpha upto 20 degree and on axis focal length upto 8 degree but same strange result for phase angle is seen every time. Please help me respectable members.
