摘要：
Proposed in this paper is a novel orthogonal Hybrid coupler applied to multi-beam electronic toll collection (ETC) systems. In this coupler, two common frequency bands of ETC system including 2.4 GHz (2.2~2.6 GHz) and 5.8 GHz (5.4~6.0 GHz) are covered to adapt different working frequency bands, and different power distribution characteristics are endowed in the two frequency bands, that is, equally orthogonal output in 2.4 GHz band and orthogonal output in the range of 0.5~7 dB in 5.8 GHz band. The proposed divider is of broad bandwidth and small circuit size, and, it is proved feasible due to the good agreement between real test results and simulation data. ©, 2015, South China University of Technology.
