Metamaterial loaded aperture coupled biodegradable star‐shaped dielectric resonator antenna for WLAN and broadband applications

摘要

Abstract >The design and development technique for the enhancement of bandwidth and gain using biodegradable star‐shaped dielectric resonator antenna (SDRA) electrified by two cross‐coupled apertures for broadband applications is presented in this article. The SDRA is fabricated using biodegradable PLA, which is a special type of polymer and made from renewable resources instead of nonrenewable petroleum‐based resources using additive manufacturing technique. Broad bandwidth of 37% is achieved by modifying rectangular dielectric resonator antenna with feeding it by two apertures (slots) of unequal length to excite different modes. The combination of the circular‐shaped split‐ring resonator has been used as a metamaterial for gain enhancement, which enhanced the maximum gain of the antenna by ～5.4 dB (82.7%). The computed average efficiency within the operating band is ～80.51%. The proposed antenna is circularly polarized at 5.8 GHz. The proposed antenna fulfills the bandwidth requirements for the IEEE 802.11a WLAN standards (5.15‐5.35 and 5.725‐5.825?GHz), and it is also suitable for various other applications such as satellite navigation systems, aeronautical and meteorological radio navigation services in C‐band. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div

本文介绍了通过用于宽带应用的两个交叉应用的可生物降解的星形介质谐振器天线（SDRA）来增强带宽和增益的设计和开发技术。使用可生物降解的PLA制造SDRA，该PLA是一种特殊类型的聚合物，并采用可再生资源而不是使用添加剂制造技术制成的不可再生石油基资源。通过改变矩形介质谐振器天线通过通过不等长度的两个孔（槽）来激发不同模式来实现37％的宽带宽。圆形分流环谐振器的组合已被用作增益增强的超材料，这提高了天线的最大增益〜5.4dB（82.7％）。操作带内的计算平均效率为约80.51％。所提出的天线在5.8GHz循环偏振。所提出的天线满足IEEE 802.11a WLAN标准的带宽要求（5.15-5.35和5.725-5.825？GHz），它也适用于C-中的各种其他应用，卫星导航系统，航空和气象无线电导航服务乐队。</ p> </摘要> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div
