Abstract

This article introduces a novel Ultra Wide Band (UWB) Multiple Input Multiple Output (MIMO) antenna with Triple-band notched characteristics. The overall dimensions of the antenna are 18 × 34 mm. The designed antenna has two similar flower-shaped radiators with L-shape strips, common ground with two flag-shaped decoupling stubs and T-shape strips for notched band characteristics. Two flag-shaped stubs are used to achieve 22 dB improved isolation. The S of the designed antenna is less than -10 dB between 3.07 GHz and 12.40 GHz, having various stopped bands of WiMAX, WLAN and X bands. The presented antenna is examined and investigated in terms of S-parameters, Mutual Coupling, Gain, Envelope Correlation Coefficient (ECC), Efficiency and Diversity Gain (DG).

摘要

本文介绍了一种具有三频段陷波特性的新型超宽带（UWB）多输入多输出（MIMO）天线。该天线的整体尺寸为18×34毫米。所设计的天线有两个带有L形条带的类似花形的辐射器、带有两个旗形去耦短截线的公共接地以及用于陷波频段特性的T形条带。两个旗形短截线用于实现22 dB的隔离改善。所设计天线的S参数在3.07 GHz至12.40 GHz之间小于-10 dB，具有WiMAX、WLAN和X频段的多个阻带。从S参数、互耦、增益、包络相关系数（ECC）、效率和分集增益（DG）等方面对所提出的天线进行了研究和分析。
