Abstract

A compact low cost multiband antenna design is proposed for future 4G Long term evolution (LTE) wireless devices of USB size and Bluetooth headsets. The printed inverted F- antenna (PIFA) type antenna structure is on a 1.6mm thick FR4 substrate. The Antenna covers LTE band-3 (1710–1880MHz)/ DCS 1800 and LTE band-7 (2500–2690MHZ) based on S11 = −6dB matching criterion. Radiation efficiency above 65% in the lower band and 80% in the upper band is achieved. Next the Multiple-Input-Multiple-Output (MIMO) configuration of this antenna is investigated. The MIMO configuration shows an envelope correlation (ρ) value of 0.5 which meets the required industry standards. Radiation efficiency is always above 60% for the MIMO configuration. Measured and simulated data are presented in this paper.

一种紧凑的多频段天线，具有MIMO实现，适用于USB大小的4G LTE无线设备

提出了一种紧凑型低成本多频段天线设计，用于未来USB尺寸的4G长期演进(LTE)无线设备和蓝牙耳机。印刷倒F天线(PIFA)型天线结构在1.6mm厚的FR4衬底上。天线覆盖LTE band-3 (1710-1880MHz)/ DCS 1800和LTE band-7 (2500-2690MHZ)，基于S11 = - 6dB匹配准则。下波段辐射效率达到65%以上，上波段辐射效率达到80%以上。然后研究了该天线的多输入多输出(MIMO)结构。MIMO配置显示包络相关(ρ)值为0.5，符合所需的行业标准。MIMO配置的辐射效率始终在60%以上。本文给出了实测和仿真数据。
