The single element consists of four crossed inclined radiating slots. In this configuration, reflection goals on the linear array are not fully achieved. For this reason a tuning element is included on some of the individual radiating elements, which consists of a pair of metallic vias that greatly enhances the reflection of longest slots. Therefore, the antenna reflection is also improved. A global antenna prototype is manufacture to check the new slot element performance in an array configuration.
