摘要

本文介绍了一种基于互补分裂环谐振器(SRR)的反射器来提高印刷槽偶极子(PSD)天线的性能。给出并研究了在反射面上刻蚀(w/o)和不刻蚀(w/o) CSRR元件时PSD天线的回波损耗、指向性和辐射方向图的数值计算结果。利用基于有限积分技术的CST Microwave Studio模拟器对所提出的设计进行了数值分析和建模。仿真结果表明，在PSD天线中加入基于csrr的反射器后，在整个工作频带内，指向性提高了0.6 dB ~ 4.25 dB，带宽提高了约2.1%。研究还表明，这种天线性能的提高是由于CSRR结构的电容负(ENG)特性。采用介电常数为电容εr= 2.2的Arlon DiClad 880衬底制作天线样机。仿真结果与实测结果吻合较好。研究表明，在天线结构中使用CSRR元件作为反射面，采用一种新的增强方法，可以很容易地提高天线的辐射性能。此外，该天线的紧凑尺寸为0.27λ × 0.41λ，适合在IEEE 802.11b/g/n/ax (2.4 GHz) WLAN应用中工作。

Complementary SRR-Based Reflector to Enhance Microstrip Antenna Performance

In this paper, complementary split ring resonator (SRR) based reflector to enhance the printed slot dipole (PSD) antenna performance is introduced. The numerically calculated return-loss, directivity and radiation pattern results of the PSD antenna, with (w/) and without (w/o) CSRR element etched on reflector plane are presented and investigated. Numerical analysis and modelling of the proposed design are carried out using CST Microwave Studio simulator based on the finite integration technique. According to the simulation results, with the inclusion of the CSRR-based reflector into the PSD antenna, the directivity is increased by values changes from 0.6 dB to 4.25 dB through the operation band, while an improvement in bandwidth (~2.1%) is seen. It is also shown that this improvement in antenna performance is due to the -negative (ENG) behavior of CSRR structures. Prototype of the proposed antenna is fabricated using Arlon DiClad 880 substrate with electrical permittivity ofεr= 2.2. A quite good agreement between simulation and measurement is obtained. In this study, it is shown that the radiation performance of the antenna can be increased easily by using the CSRR element as a reflector in the antenna structure with a new enhancement approach. Also, the proposed antenna with a compact size of 0.27λ× 0.41λ is appropriate for operating in IEEE 802.11b/g/n/ax (2.4 GHz) WLAN applications.

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 The ACES Journal welcomes original, previously unpublished papers, relating to applied computational electromagnetics.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.
