Abstract

This paper presents a multiband antenna for WLAN and LTE MIMO systems based on a thin-film substrate. Which has ε_r= 3.2 and thickness of 0.3 mm. the proposed antennas consist of a two-ring patch monopole and a ground patch on the back, built using conductive material is copper with thickness of 0.1 mm. When integrated with the substrate material, makes the antenna thickness at 0.5 mm and its size is 55.4 mm x 110.4 mm (W×L). The measurement result of antenna shows the frequency response range between 1GHz-3GHz that is operation frequency of multiband. Which is cover WLAN band (2.4GHz), LTE 1800MHz band 3 (UL1710-1785MHz, DL1805-1880MHz), LTE 2100MHz band 1 (UL1920-1980MHz, DL2110-2170MHz), and LTE 2300MHz band 40 (2300- 2400GHz) and LTE 2600MHz band 38 (2570-2620MHz) at S11 less than -6 dB. In addition, the prototype antenna has average gain of 3.9 dBi and a correlation coefficient less than 0.5 over of the operation frequency. Therefore, the prototype antenna can be the measurement for other performance and applied to the LTE mobile network.

用于WLAN和LTE MIMO系统的多波段薄膜天线

本文提出了一种基于薄膜衬底的WLAN和LTE MIMO系统多频段天线。该天线ε_r= 3.2，天线厚度为0.3 mm，由双环贴片单极子和背面地贴片组成，采用厚度为0.1 mm的导电材料铜制成。当与衬底材料集成时，天线厚度为0.5 mm，尺寸为55.4 mm × 110.4 mm (W×L)。天线的测量结果表明，频率响应范围在1GHz-3GHz之间，即多频段工作频率。其中包括WLAN频段(2.4GHz)， LTE 1800MHz频段3 (UL1710-1785MHz, DL1805-1880MHz)， LTE 2100MHz频段1 (UL1920-1980MHz, DL2110-2170MHz)， LTE 2300MHz频段40 (2300- 2400GHz)和LTE 2600MHz频段38 (2570-2620MHz)， S11小于-6 dB。此外，原型天线的平均增益为3.9 dBi，相关系数小于0.5 /工作频率。因此，原型天线可以作为其他性能的测量，并应用于LTE移动网络。
