A squintless slot-antenna array (2-D), built on a single substrate integrated waveguide (SIW) is shown. The effort needed for designing a suitable feeding network in SIW technology is justified in view of obtaining lightweight, low-profile, and low-cost antennas for many applications, including direct broadcast satellite. A proper definition of an "H"-shaped subarray, made of four slot-pairs, is used to improve the input matching over a wide band. This choice allows remarkable simplification of the fabrication process, as the slots are cut directly in one of the metallic planes forming the SIW.
