    Hexagonal CORPS-BFN to feed OLAF SAR instrument
    (IEEE, 2021) Biurrun Quel, Carlos; Iriarte Galarregui, Juan Carlos; Ederra Urzainqui, Íñigo; Río Bocio, Carlos del; Institute of Smart Cities - ISC
    The 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.
