摘要

提出了一种新型的紧凑型任意功率划分双带支路耦合器。采用传统的半波长短端存根耦合器实现双波段操作。此外，可以通过改变传输线的特性阻抗来调节频率。为了进行实际验证，采用微带技术构建了工作在0.9/1.8GHz的支路耦合器($\varepsilon_{\ maththrm {r}}=2.65，\ h=0.5 \text{mm}$)并进行了测试。实测结果与模拟结果吻合较好。

Compact Dual-band Branch-Line Coupler with Short-ended Stubs

A novel compact dual-band branch line coupler with arbitrary power division is proposed. A conventional coupler loaded with half-wavelength short-ended stubs is adopted to realize the dual-band operations. Moreover, the frequency is tunable by changing the characteristic impedance of the transmission line. For practical verification, a branch line coupler ($\varepsilon_{\mathrm{r}}=2.65,\ h=0.5 \text{mm}$) operation at 0.9/1.8GHz is constructed in microstrip technology and tested. The measured results are in good agreement with the simulated ones.
