摘要

提出了一种紧凑的八端口共面波导(CPW)馈电超宽带(UWB)多输入多输出(MIMO)天线，该天线具有带缺口特性，尺寸较小，为54×54×0.8 mm3。8端口MIMO天线由4个2端口MIMO天线组成。对于每个双端口MIMO天线，两个单极天线元件被印在FR4基板上并彼此垂直放置。为了增加阻抗带宽和改善隔离，在两个辐射元件的中间放置一个存根。通过在每个辐射元件上分别刻蚀两个l型谐振槽来实现带陷波特性。测量了MIMO天线的S11反射系数、耦合隔离、辐射方向图、峰值增益和辐射效率。采用包络相关系数(ECC)和总主动反射系数(TARC)对天线的MIMO性能进行了分析和评价。

A Compact Eight-port CPW-fed UWB MIMO Antenna with Band-notched Characteristic

A compact eight-port coplanar waveguide (CPW)-fed ultra-wideband (UWB) multiple-input-multiple-output (MIMO) antenna with band-notched characteristics in a small size of 54×54×0.8 mm3 is proposed in this paper. The eight-port MIMO antenna consists of four two-port MIMO antennas. For each two-port MIMO antenna, two monopole antenna elements are printed on the FR4 substrate and placed perpendicularly to each other. To increase impedance bandwidth and improve the isolation, a stub is positioned in the middle of two radiating elements. The band-notched characteristic are achieved by etching two L-shaped resonator slots on each radiating elements, respectively. The S11 reflection coefficients, coupling isolation, radiation patterns, peak gain and radiation efficiencies of the MIMO antenna are measured. The MIMO performance of the proposed antenna is analyzed and evaluated by the envelope correlation coefficient (ECC) and total active reflection coefficient (TARC).

期刊介绍： The ACES Journal is devoted to the exchange of information in computational electromagnetics, to the advancement of the state of the art, and to the promotion of related technical activities. A primary objective of the information exchange is the elimination of the need to "re-invent the wheel" to solve a previously solved computational problem in electrical engineering, physics, or related fields of study. The ACES Journal welcomes original, previously unpublished papers, relating to applied computational electromagnetics. All papers are refereed. A unique feature of ACES Journal is the publication of unsuccessful efforts in applied computational electromagnetics. Publication of such material provides a means to discuss problem areas in electromagnetic modeling. Manuscripts representing an unsuccessful application or negative result in computational electromagnetics is considered for publication only if a reasonable expectation of success (and a reasonable effort) are reflected. The technical activities promoted by this publication include code validation, performance analysis, and input/output standardization; code or technique optimization and error minimization; innovations in solution technique or in data input/output; identification of new applications for electromagnetics modeling codes and techniques; integration of computational electromagnetics techniques with new computer architectures; and correlation of computational parameters with physical mechanisms.
