The article presents a Co-planar Waveguide (CPW) fed antenna of a low-profile, simple geometry, and compact size operating at the dual band for ISM and WLAN applications for 5G communication devices. The antenna has a small size of 30 mm × 18 mm × 0.79 mm and is realized using Rogers RT/Duroid 5880 substrate. The proposed dual-band antenna contains a CPW feedline along with the triangular patch. Later on, various stubs are loaded to obtain optimal results. The proposed antenna offers a dual band at 2.4 and 5.4 GHz while covering the impedance bandwidths of 2.25-2.8 GHz for ISM and 5.45-5.65 GHz for WLAN applications, respectively. The proposed antenna design is studied and analyzed using the Electromagnetic (EM) High-Frequency Structure Simulator (HFSSv9) tool, and a hardware prototype is fabricated to verify the simulated results. As the antenna is intended for on-body applications, therefore, Specific Absorption Rate (SAR) analysis is carried out to investigate the Electromagnetic effects of the antenna on the human body. Moreover, a comparison between the proposed dual-band antenna and other relevant works in the literature is presented. The results and comparison of the proposed work with other literary works validate that the proposed dual-band antenna is suitable for future 5G devices working in Industrial, Scientific, Medical (ISM), and Wireless Local Area Network (WLAN) bands.
本文介绍了一种共面波导（CPW）馈电天线，该天线外形低矮、几何结构简单、尺寸紧凑，工作在双频段，适用于5G通信设备的ISM和WLAN应用。该天线尺寸小，为30 mm×18 mm×0.79 mm，采用罗杰斯RT/Duroid 5880基板实现。所提出的双频段天线包含一条CPW馈线以及三角形贴片。随后，加载了各种短截线以获得最佳结果。所提出的天线在2.4 GHz和5.4 GHz提供双频段，同时分别覆盖ISM频段2.25 - 2.8 GHz和WLAN应用频段5.45 - 5.65 GHz的阻抗带宽。使用电磁（EM）高频结构模拟器（HFSSv9）工具对所提出的天线设计进行了研究和分析，并制作了硬件原型以验证模拟结果。由于该天线旨在用于人体应用，因此进行了比吸收率（SAR）分析，以研究天线对人体的电磁影响。此外，还给出了所提出的双频段天线与文献中其他相关工作的比较。所提出工作的结果以及与其他文献作品的比较验证了所提出的双频段天线适用于未来工作在工业、科学、医疗（ISM）和无线局域网（WLAN）频段的5G设备。
