Miniaturized Phase-Shifting Power Divider Based on Slow-Wave Substrate Integrated Waveguide
摘要
Abstract
In this paper,a miniaturized phase-shifting power divider based on slow-wave substrate integrated wave-guide(SW-SIW)is proposed for the functional integration of phase shifter and power divider.The design features two out-put 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.关键词
