Re: ie3d simulation procedure for design 4 element patch ant
hi sakthivelu,
Copy and paste the radiator element at the required distance (normally 0.72 to 0.8λ) then construct the feed network by joining those radiator elements and simulate the structure by assigning port to the input of feed n/w.
r
U can model antenna elements as one structure and feed n/w as other ,simulate those structure separately, Radiation from the antenna elements and feed network are merged to give result as a whole.
For Further clearance u can go thr chapter-13 of IE3D Manual(Simulation of Antenna Arrays)
