摘要：
In this paper, a miniaturized phase-shifting power divider based on slow-wave substrate integrated waveguide (SW-SIW) is proposed for the functional integration of phase shifter and power divider. The design features two output branches with equal lengths and widths to achieve a 30° phase shift. One output branch is realized by a conventional substrate integrated waveguide (SIW), while the other output branch is loaded a complementary split-ring resonator (CSRR) on the upper metal surface to replace the continuous metal surface of the conventional SIW, and the CSRR is evolved from the classic CSRR structure. Meanwhile, a metallized via-hole is added inside the CSRR to reduce the phase instability caused by the loading of the CSRR, so a SW-SIW is realized, and the cut-off frequency and phase velocity are reduced. The measured results show that the reflection coefficient |S11| of the phase-shifting power divider is less than ‒10 dB in the frequency band of 9.0~11.8 GHz, the relative operating bandwidth is 26.9%, and the insertion loss is less than 1.3 dB. The phase difference between the two output ports is stable at 30° ± 3°, and the amplitude difference is less than 1.4 dB realizing equal power distribution. The designed phase-shifting power divider has a small size and low manufacturing cost, which is suitable for application in phased-array antennas. © 2024 Chinese Institute of Electronics.
