In March, 2020 we rolled out CENOS Antenna Design software's beta version testing. Based on the feedback provided by our beta testers we improved our software production version.
Here's a simulation of a two-element microstrip patch array done by one of our most committed beta-testers Andreas Rosenberg (Microwave Development Engineer at Weibel Scientific - Copenhagen, Denmark):
Andreas: “The antenna was simulated and created in such way that we could verify a new setup for an antenna measurement facility, that was made as part of a special course at the Technical University of Denmark (DTU)"
After creating the simulation Andreas decided to do a far field radiation pattern accuracy comparison between CENOS, Ansys HFSS and actual measurements done in DTU's test lab:
As you can see, the results are very similar and prove that CENOS, although in beta version, can complete such tasks with high accuracy.
Andreas has helped us a lot, and in reward was granted a free perpetual license to use CENOS Antenna Design forever.
