摘要

提出了一种多输入多输出(MIMO)超宽带(UWB)印刷弯曲天线，适用于MB-OFDM ECMA-368系统与无线通用串行总线(WUSB)加密狗的集成。该天线由两个天线单元组成，总面积为18 X 53 mm2。每个天线单元都是由共面波导(CPW)馈电的简单修正折叠单极子。提出了MIMO超宽带cpw馈电弯曲天线结构的设计过程，分为四个简单步骤。实验结果表明，该设计具有良好的阻抗带宽(2.95 ~ 18.55 GHz)，分数带宽(FBW)为147.2%。此外，该天线具有低的包络相关系数(ECC)、良好的分集增益(DG)、低的总主动反射系数(TARC)和全向辐射方向图。利用提取的发射和接收UWB天线传输函数，在更真实的传输信道场景下，评估了MIMO超宽带cpw馈电弯曲天线存在时，整个MB-OFDM ECMA-368系统的误码率(BER)。

MIMO CPW-Fed Bent Antenna Based USB Dongle for ECMA-368 WPANs

A multiple-input-multiple-output (MIMO) ultra-wideband (UWB ) printed bent antenna, suitable for MB-OFDM ECMA-368 system integration with the wireless universal serial-bus (WUSB) dongle is proposed. The antenna consists of two antenna elements with an overall area of 18 X 53 mm2. Each antenna element is a simple modified folded-monopole fed by a coplanar waveguide (CPW). The design process of proposed MIMO UWB CPW-fed bent antenna configuration is presented in four simple steps. Experimental results show that the proposed design has a good impedance bandwidth in the range of 2.95–18.55 GHz with 147.2% fractional bandwidth (FBW). Moreover, the proposed antenna enjoys, low envelope correlation coefficient (ECC), good diversity gain (DG), low total active reflection coefficient (TARC) and omnidirectional radiation patterns. The bit error rate (BER) of the overall MB-OFDM ECMA-368 system with the existence of the proposed MIMO UWB CPW-fed bent antenna is evaluated in more realistic transmission channel scenario by using the extracted transmitting and receiving UWB antennas transfer functions.
