1. Compare the radiation pattern of the antenna for both the initial and the optimised antenna design. The gain in the back-lobe region (between 90° and 180°) is reduced to -7 dB. The gain in the main-lobe region (between 0° and 30°) is above 8 dB.
Tip: To view the masks on the same graph, drag each mask from the model browser onto the graph, then apply a scale of 180 (Transform axis) to each mask's trace.
2. View the optimum parameter values found during the optimisation search in the optimisation log file.
