ABSTRACT:
A waveguide-to-stripline transition includes a stripline portion (14) that fits over an opening in one end of waveguide (12). The stripline portion has a cavity defined by an upper ground-plane conductor (20), a lower ground-plane conductor (22), and a rectangular arrangement of plated-through holes (28) that electrically connect the upper ground-plane conductor (20) to the lower ground-plane conductor (22). The upper ground-plane conductor (20) is etched to provide an aperture (32) with a conductive crosspiece (34) extending longitudinally across it. A plated-through hole (36) connects the crosspiece (34) to the center conductor (26) to provide a T-shaped feed element in the cavity. As compared with prior-art waveguide-to-stripline transitions, this transition is mechanically stronger and has higher power-handling capability.
