- Abstract
A pair of dual-band closely spaced MIMO monopole antenna array working at WLAN 2.45/5.25GHz with a dual-band coupled resonator structure for decoupling is proposed, the edge-to-edge distance of which is 0.0735λ0 at 2.45GHz and 0.1575λ0 at 5.25GHz. Simulation and measurement on coupled antennas and decoupled antennas indicate that mutual coupling reductions of 24.52dB and 26.57dB at two frequencies are achieved. With good impedance matching, improved total efficiency and increased channel capacity, the proposed structure owns good applicability, compact size and effective decoupling capability, and is promising in the application of wireless terminal MIMO system.
