Abstract

A compact metamaterial inspired antenna operate at LTE, Bluetooth and WiMAX frequency band is introduced in this paper. For the lower band, the design utilizes an outer square metallic strip forcing the patch to radiate as an equivalent magnetic-current loop. For the upper band, another magnetic current loop is created by adding metamaterial structure near the feed line on the patch. The metamaterial inspired antenna dimension of 42 × 32 mm compatible to wireless devices. Finite integration technique based CST Microwave Studio simulator has been used to design and numerical investigation as well as lumped circuit model of the metamaterial antenna is explained with proper mathematical derivation. The achieved measured dual band operation of the conventional antenna are sequentially, 0.5610.578 GHz, 2.3462.906 GHz, and 2.913.49 GHz, whereas the metamaterial inspired antenna shows dual-band operation from 0.600.64 GHz, 2.673.40 GHz and 3.613.67 GHz, respectively. Therefore, the metamaterial antenna is applicable for LTE and WiMAX applications. Besides, the measured metamaterial antenna gains of 0.153.81 dBi and 3.473.75 dBi, respectively for the frequency band of 2.673.40 GHz and 3.613.67 GHz.

摘要

本文提出了一种工作在 LTE、蓝牙和 WiMAX 频段的紧凑型超材料天线。对于较低频段，设计利用外部方形金属条迫使贴片辐射作为等效磁流环。对于较高频段，通过在贴片上的馈线附近添加超材料结构，创建另一个磁流环。超材料天线的尺寸为 42×32mm，与无线设备兼容。基于有限积分技术的 CST Microwave Studio 模拟器已被用于设计和数值研究，并且解释了超材料天线的集总电路模型，并进行了适当的数学推导。传统天线的实测双频工作频率分别为 0.5610.578GHz、2.3462.906GHz 和 2.913.49GHz，而超材料激励天线的双频工作频率分别为 0.600.64GHz、2.673.40GHz 和 3.613.67GHz。因此，超材料天线适用于 LTE 和 WiMAX 应用。此外，超材料天线在 2.673.40GHz 和 3.613.67GHz 频段的增益分别为 0.153.81dBi 和 3.473.75dBi。
