摘要：

The microstrip dual-band coupler with coupled-line ring has been provided. Within the proposed couplers, a coupled line with a half/quarter wavelength and two quarter-wavelength Schiffman phase shifters are adopted. The proposed couplers can not only be operated at two flexible frequencies with both 90 degrees phase differences, but also provides the required output power ratio at the designed dual frequencies by the derived formulae. In order to verify the proposed design methodology, two experimental dual-band couplers are designed and fabricated.
