The utilization of a corporate topology in the feeding network prevents the antenna from suffering an unintended main lobe tilt dispersion. Nevertheless, the interelement spacing increases, and so does the Side-Lobe Level. Reducing this spacing implies closer discontinuities, such as bends and T-junctions. This degrades the reflection coefficient. Hence, a tradeoff solution has been designed and manufactured, achieving a Side-Lobe Level better than -11 dB and a measured bandwidth similar to the expected in the simulation stage, being 4.1 \% at -10 dB. The measured gain reaches 13.27 dB, which corresponds to an 86\% radiation efficiency.}, keywords = {antenna, array, corporate feed, linear polarization., SIW, stacked patch}, author = {E Garcia-Marin and J L Masa-Campos and P Sanchez-Olivares} }
