摘要

摘要在这项研究工作中，介绍了一种单极子结构的紧凑型微带天线的设计和分析，该天线具有 64.86% 的宽带宽。该结构的主辐射器是基于分形的几何形状，其形状为半科奇雪花，地平面是局部的（缺陷地）。通过分析建模介绍了该天线的设计方法，并制作了结构原型以验证其性能。测量结果表明，该天线在 4-7.84 GHz 范围内具有 -10 dB 带宽，从而以全向辐射模式覆盖了大约 C 波段。拟议的天线在 7.2 GHz 时的峰值增益为 3.4 dBi，在 5.8 GHz 时的整体尺寸为 0.33λ × 0.49λ × 0.03λ。与最近报道的一些设计相比，该结构更为紧凑，在 5.8 GHz 时的读取距离为 1.98 厘米。读取范围和传播测试验证表明，这种紧凑型宽带平面天线适用于各种短距离读取器应用。

A modified Koch‐snowflake monopole antenna for short‐range radio frequency identification reader and C band applications

SummaryIn this research work, the design and analysis of a compact microstrip antenna having a monopole structure with 64.86% of wide bandwidth is presented. The main radiator of the structure is a fractal‐based geometry with the shape of a half‐Koch snowflake, and the ground plane is partial (defected ground). The design methodology of the antenna is presented using analytical modeling, and the structure prototype is fabricated to verify the performance. Measurement outcomes confirm the −10 dB bandwidth in range of 4–7.84 GHz, thus covering approximately the C‐band with omnidirectional radiation patterns. The proposed antenna shows a peak realized gain of 3.4 dBi at 7.2 GHz and has an overall dimension of 0.33λ × 0.49λ × 0.03λ, at 5.8 GHz. The structure is found compact compared to some recently reported designs and the read range is found to be 1.98 cm at 5.8 GHz. The read range and validation of the propagation test indicate the suitability of the compact and wideband planar antenna in various short‐range reader applications.

期刊介绍： The International Journal of Communication Systems provides a forum for R&D, open to researchers from all types of institutions and organisations worldwide, aimed at the increasingly important area of communication technology. The Journal''s emphasis is particularly on the issues impacting behaviour at the system, service and management levels. Published twelve times a year, it provides coverage of advances that have a significant potential to impact the immense technical and commercial opportunities in the communications sector. The International Journal of Communication Systems strives to select a balance of contributions that promotes technical innovation allied to practical relevance across the range of system types and issues. The Journal addresses both public communication systems (Telecommunication, mobile, Internet, and Cable TV) and private systems (Intranets, enterprise networks, LANs, MANs, WANs). The following key areas and issues are regularly covered: -Transmission/Switching/Distribution technologies (ATM, SDH, TCP/IP, routers, DSL, cable modems, VoD, VoIP, WDM, etc.) -System control, network/service management -Network and Internet protocols and standards -Client-server, distributed and Web-based communication systems -Broadband and multimedia systems and applications, with a focus on increased service variety and interactivity -Trials of advanced systems and services; their implementation and evaluation -Novel concepts and improvements in technique; their theoretical basis and performance analysis using measurement/testing, modelling and simulation -Performance evaluation issues and methods.
