Abstract

This paper presents a novel metamaterial-inspired star shaped microstrip patch antenna (MPA) designed for enhanced performances in wireless applications. Unlike conventional MPA designs that suffer from low gain, narrow bandwidth, and poor radiation efficiency, the proposed antenna introduced a circular ring metamaterial (CRM) structure with cross shaped defected ground structure (Cr-DGS) to significantly enhance gain, directivity, and radiation characteristics. The antenna is designed on FR-4 substrate material with a relative permittivity of 4.4 and loss tangent of 0.025, and resonating frequency of 2.82 GHz using a coaxial probe feeding mechanism for impedance matching. The antenna is designed with an overall dimension of \(50\, \times 50 \times 1.6\) mm³, which is operated at 1 GHz to 4 GHz. A key innovation lies in the integration of symmetric CRM units and star shaped patch, which facilitates uniform current distribution and superior electromagnetic field confinement. Simulation and experimental results confirm maximum gain values of 7.3 dB and directivity of 6.6 dB, which outperform several recent benchmark designs. This unique combination of geometry and metamaterial engineering establishes the proposed model as a compact, high-performance solution for next generation wireless systems, including IoT and 5G.

增强增益与CRM启发星形微带贴片天线无线应用

本文提出了一种新型的星形微带贴片天线（MPA），用于提高无线应用中的性能。与传统MPA设计增益低、带宽窄、辐射效率差不同，该天线采用环形超材料（CRM）结构和十字形缺陷接地结构（Cr-DGS），显著提高了增益、指向性和辐射特性。天线设计在FR-4衬底材料上，相对介电常数为4.4，损耗正切为0.025，谐振频率为2.82 GHz，采用同轴探针馈电机构进行阻抗匹配。天线的整体尺寸设计为\(50\, \times 50 \times 1.6\) mm3，工作频率为1 GHz至4 GHz。一个关键的创新在于对称CRM单元和星形贴片的集成，这有助于均匀的电流分布和优越的电磁场约束。仿真和实验结果证实，最大增益值为7.3 dB，指向性值为6.6 dB，优于最近的几个基准设计。这种几何和超材料工程的独特结合使所提出的模型成为下一代无线系统（包括物联网和5G）的紧凑、高性能解决方案。
