Abstract :
Substrate integrated waveguides technology has been implemented to develop a compact feed network for a slot antenna array. Various transitions design rules have been developed and implemented including compact “T” and “Y” junctions, layer to layer couplers, and a wide band CPWG to SIW transition. The feed network is optimized to have a low overall insertion loss while supporting the required bandwidth through optimizing the dimension of junctions on each stage.
