Del-Río, "Hexagonal CORPS-BFN to feed OLAF SAR Instrument," 2021 15th European Conference on Antennas and Propagation (EuCAP), 2021, pp. 1-5, doi: 10.23919/EuCAP51087.2021.9411174.978-88-31299-02-22164-334210.23919/EuCAP51087.2021.9411174https://academica-e.unavarra.es/handle/2454/41959The concept of Coherently Radiating Periodic Structures-based Beam Forming Networks is applied to feed OLAF (OverLapped SubArray Fed) antenna for SAR Instrument at L-Band. The proper feeding of this system requires the multiple beams to be highly overlapped, and that is generated by a CORPS-BFN using a new 4-port Gysel power combiner/divider implemented in a suspended stripline technology. The network provides high isolation between inputs/outputs, low insertion loss, great return loss and the desired ovelapping of the different beams.5 p.application/pdfeng© 2021 IEEE.
