In this paper, a W-band T-junction power divider based on rectangular microcoaxial structure is proposed. Rectangular microcoaxial line is a three dimensional (3D) structure with the merits of wide operation bandwidth, low loss and high integration, which is suitable for the design of radio frequency (RF) devices. A two-way power divider is designed based on the rectangular microcoaxial structure. And the two-way power divider is expanded into a four-way power divider to further illustrate the design method. Moreover, a back-to-back configuration including two identical two-way power divider is fabricated and measured. The insertion loss of the back-to-back configuration is about 0.11-1.18 dB in W band, which agrees with the simulation one reasonably and shows good performance.
