摘要

本文提出了一种双频工作的小型MIMO天线。S11 <−9.5 dB可在2.576-3.728 GHz的下频段和5.14-5.88 GHz的上频段实现，覆盖2.572-2.62 GHz (3GPP)、2.6-2.69和3.3-3.7 GHz (4G Wi-Max)以及5.15-5.35、5.725-5.875 GHz (WLAN)应用。使用接地槽和接地扩展等隔离技术在两个工作频带中实现S12 <−20 dB。预制天线结构的实测结果与仿真结果吻合。MIMO性能参数ECC在低频段< 0.02，高频段< 0.04，辐射方向图稳定。所提出的天线尺寸为28×35×28×1.6 mm3，这使得它可以在便携式设备中使用。

Dual-band compact MIMO antenna for 3G, Wi-MAX and WLAN applications

This paper presents a compact MIMO antenna with dual band operation. S¹¹ < −9.5 dB is achieved over lower band of 2.576–3.728 GHz and upper band of 5.14–5.88 GHz which covers 2.572–2.62 GHz (3GPP), 2.6–2.69 and 3.3–3.7 GHz (4G Wi-Max) and 5.15–5.35, 5.725–5.875 GHz (WLAN) applications. Isolation techniques like ground slots and ground extension are used to achieve a S12 < −20 dB in both the operating bands. The measured results of fabricated antenna structure match with the simulation results. MIMO performance parameter ECC in the lower band is < 0.02 and in higher band is < 0.04 with stable radiation pattern. The proposed antenna has dimension of 28×35×28×1.6 mm³ which makes it feasible to be used within portable devices.
