Abstract

This paper is devoted to a novel Electromagnetic Band Gap (EBG) single-feed circularly polarized microstrip EBG antenna with compact size proposed for C-Band applications. The antenna structure will include eight slits introduced at the boundary and the corners in the radiating square patch with a cross-slot at the center. The provided study will effectively approve the various proposed structures and interest occupied by these types of antennas in the enhancement of output parameters (gain, directivity, radiation efficiency, and bandwidth) without much affecting the operating bandwidth at C-band. At first, the concept and the realization of a directive and circularly polarized antenna using an electromagnetic band gap material whose circular polarization is generated by the structure itself is discussed. The analysis and simulation results are presented for an antenna operating at 6.1 GHz using computer Simulation Technologies (CST). Furthermore, the new compact circular polarized EBG antenna, compared to experimental results, will confirm the pre-studied goal of these kinds of antennas such as radiation efficiency, polarization purity, radiation efficiency, high directivity, and gain.

一种高效的交叉槽加载紧凑型电磁带隙天线的分析与研制

本文研究了一种新型的c波段单馈圆极化微带电磁带隙(EBG)天线。天线结构将包括在边界处引入的8个狭缝和在中心处具有交叉狭缝的辐射方形贴片的角。所提供的研究将有效地批准这些类型的天线在增强输出参数(增益、指向性、辐射效率和带宽)方面所提出的各种结构和兴趣，而不会对c波段的工作带宽产生太大影响。本文首先讨论了利用电磁带隙材料实现定向圆极化天线的概念和实现方法，这种材料的圆极化是由结构本身产生的。利用计算机仿真技术(CST)对工作在6.1 GHz的天线进行了分析和仿真。通过与实验结果的对比，验证了该天线的辐射效率、极化纯度、辐射效率、高指向性和增益等目标。

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 The ACES Journal welcomes original, previously unpublished papers, relating to applied computational electromagnetics.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