            Abstract : 
In order to improve the gain bandwidth of a 16×16-element plate-laminated-waveguide slot array, the reflection bandwidth of the 2×2-element sub-array is designed. The reflection bandwidth of VSWR <; 1.5 is enhanced from 9.2% to 20.4%. The bandwidth of the gain above 32.0 dBi is successfully expanded from 12.8% to 20.8% by simulation.
