【 摘 要 】

A decoupling method between two tri-band antennas for WLAN/WiMAX applications is presented. A monopole is first designed with tri-band characteristic; three resonating frequencies are generated by three separate resonators. Then, two tri-band monopoles are employed to develop a MIMO antenna system. The resonators of low band can reduce the mutual coupling for two higher bands by suppressing surface wave propagation. Finally, coupling reduction at low band is achieved by a Ω-shaped metal line to neutralize original coupling. The proposed MIMO antenna covers the 2.4/5.8 GHz WLAN and 3.5 GHz WiMAX bands, with the measured mutual coupling lower than −18 dB.
