  1. I am trying to simulate a 4x4 array of microstrip patch antennas. First, the simulation was done on an infinite ground plane which resulted in 15.65 dBi of boresight gain. However, on replacing the infinite ground plane with a finite one (and solving the model with MLFMM solver to reduce computation time), the radiation pattern undergoes complete degradation with no mainlobe whatsoever. Why is this happening? The same model has been simulated using other commercially available EM solvers on finite ground planes, and the results obtained are as expected. I am attaching a figure that compares the radiation pattern, of the 4x4 array on finite ground plane in the YZ-plane (phi = 90 deg plane), obtained via different EM solvers. The .cfx files for the 4x4 array are also attached. Thank you in advance. 4by4_InfiniteGnd.cfx 4by4_FiniteGnd.cfx
  2. Hi Expert Feko, Good day, I would like to know how to design an array antenna from a design of single antenna operates at 2.6Ghz, how we want to transform and copy the single antenna so that we can make it array, in CST it has the transform and copy button so that we did not need to design it repeatedly the patch on top of the substrate, so hopefully that you guys can help me by providing some step. Thank You. Attach here is my single antenna pika.cfx
