摘要：
In the paper, we describe analysis of Vivaldi antenna array aimed for microwave image application and SAR application operating at Ka band. The antenna array is fed by a SIW feed network for its low insertion loss and broadband performances in millimeter wave range. In our proposal we have replaced the large feed network by a simple relatively broadband network of compact size to reduce the losses in substrate integrated waveguide (SIW) and save space on PCB. The feed network is power 8-way divider fed by a wideband SIW-GCPW transition and directly connected to the antenna elements. The final antenna array will be designed, fabricated and obtained measured results will be compared with numerical ones.
