摘要：

A dual-band 90 degrees unit module with harmonic suppression (HS) is proposed. This unit module consists of a pair of back-to-back stepped impedance sections and an open stub. The unit module is realised by synthetic transmission lines, and it is successfully implemented into a novel miniature dual-band (2.45/5.8-GHz) rat-race coupler with HS (suppression level 16 dB, 6.8-13 GHz). Compared with traditional 1.5 microstrip ring hybrid, the proposed dual-band rat-race with HS only occupies 13.84% of its area.
