Abstract

SummaryA low profile, concave conformal ring cylindrical dielectric resonator antenna (CDRA) employing frequency selective surface (FSS) using split ring resonator (SRR) for wideband and high gain applications is presented. The ring CDRA loaded with the monopole is designed to excite the TM01δ mode to increase the antenna's bandwidth. The effect of a curved ground plane (GP) on the radiation performance of CDRA is studied. A 5 × 5 array of the SRR is placed above the conformal GP at a far‐field distance optimized to (2n ± 1) λ/4 from the radiating element to enhance the gain of the proposed structure. The planar CDRA with FSS is compared with the conformal CDRA with FSS and a 4.3 GHz improvement in bandwidth is observed due to the multiple reflection and surface reflection leading to a 3.2 dBi improvement in gain. An impedance bandwidth of 51.8% (5 to 8.5 GHz) with a maximum gain of 8.7 dBi at 7.3 GHz resonant frequency and 99% radiation efficiency at 5.9 GHz is offered by the proposed antenna with FSS. Additionally, the proposed CDRA has a low profile of 0.12 λ0 where λ0 is the lower cut‐off frequency's wavelength. A good agreement is observed between the simulated and measured results.

用于 ISM 和 C 波段应用的装有分裂环谐振器的低剖面高增益凹面共形环圆柱介质谐振器天线

摘要本文介绍了一种低剖面、凹面共形环形圆柱介质谐振器天线（CDRA），该天线采用频率选择表面（FSS），使用分裂环谐振器（SRR），适用于宽带和高增益应用。加载单极子的环 CDRA 设计用于激发 TM01δ 模式，以增加天线的带宽。研究了弯曲地平面（GP）对 CDRA 辐射性能的影响。在共形 GP 上方放置了一个 5 × 5 的 SRR 阵列，与辐射元件的远场距离优化为 (2n ± 1) λ/4，以提高拟议结构的增益。带 FSS 的平面 CDRA 与带 FSS 的共形 CDRA 相比，由于多重反射和表面反射，带宽提高了 4.3 GHz，增益提高了 3.2 dBi。带 FSS 的拟议天线的阻抗带宽为 51.8%（5 至 8.5 GHz），在 7.3 GHz 谐振频率下的最大增益为 8.7 dBi，在 5.9 GHz 下的辐射效率为 99%。此外，拟议的 CDRA 具有 0.12 λ0 的低剖面，其中 λ0 是下截止频率的波长。模拟和测量结果之间的一致性很好。

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.
