Summary:
This paper presents design of a slot array for an alternatingphase fed single-layer slotted waveguide array with a latticed plate. The latticed plate with a relatively large thickness is put on a slotted plate and they are tightly fixed by screws on a groove feed structure without electrical contact such as brazing. Slot coupling in a waveguide slot with a cavity, which is a radiation element of the slot array, is obtained by MoM with mutual coupling effects in the external region taken into account for the array design. The slot array with 25 elements is designed for uniform aperture distribution in 76 GHz. Validity of the design is confirmed by near field measurement of the prototype antenna.
