“…The rectangular waveguides, due to advantages of low loss, high Q value, large power capacity, and excellent shielding, are usually attractive for many applications. Various designs including waveguide hybrids, magic‐T junctions, and waveguide T‐junctions have been reported to fulfill power dividing and combining . However, these structures have large dimensions which impede their applications for high‐density integration in millimeter‐wave band, especially in W‐band.…”

“…Various designs including waveguide hybrids, magic-T junctions, and waveguide T-junctions have been reported to fulfill power dividing and combining. [1][2][3][4][5][6][7] However, these structures have large dimensions which impede their applications for high-density integration in millimeter-wave band, especially in W-band. Thus, millimeter-wave dividers/combiners using a structure to combine waveguide and transition become more and more popular in millimeter-wave designs.…”

In this article, a broadband microstrip‐to‐waveguide transition with antisymmetric tapered probe as well as a W‐band power divider/combiner using dual proposed antisymmetric tapered probes is presented. Because of tapered microstrip shapes and metallic steps, the proposed transition is proved to be broadband, efficient, and compact. The insertion loss of the transition sample is less than 0.56 dB between 75 GHz and 100 GHz. Under the assistance of the gradually changed waveguide and dual parallel tapered probes, the operating band of the power divider/combiner has been significantly improved, which is adequate to work in the whole W‐band. A back‐to‐back prototype of the divider/combiner is fabricated and measured. The measured insertion loss of the single divider/combiner is less than 0.29 dB between 90 GHz and 100 GHz, and agrees well with the simulations. Because the circuit size is smaller than 8.0 mm × 2.2 mm (Thanks to the excellent performance and compact size), the proposed design can find wide applications in miniaturized MCM/MMIC systems.
