This letter presents a miniaturized dual-mode composite- right/left-handed line resonator with wide harmonic suppression. The pure right-handed microstrip transmission line adopt 36° electrical length instead of 90°, thus the size of the dual-mode filter can be reduced significantly meanwhile the spurious response suppression are improved effectively. A prototype filter is designed and implemented at 730 MHz, which not only has a size reduction of 92% against a conventional dual-mode filter, but also exhibits harmonic suppression characteristics over a decade bandwidth.
