摘要

Abstract >This work proposes a new methodology for widening the bandwidth of a reflectarray (RA) antenna. The narrow impedance of the conventional dielectric RA can be effectively widened on the basis of the gradual impedance matching principle. A multilayer element can realize impedance matching to free space by suitably choosing the different diameters in different layers of the drilled air‐vias. Besides, a series of air‐vias with varying diameters changes the resonance frequencies and partially overlapped bandwidth between one another, which results in widening the bandwidth. To validate the wideband RA antenna design, a circular RA prototype with diameter of 96?mm is simulated, fabricated, and measured. The measured RA exhibits an improved 1‐dB gain bandwidth of 18.4%. A peak gain of 25.18 dBi with maximum aperture efficiency of 52.18% is obtained. The significant experimental performance improvement confirms that bandwidth can be efficiently broadened by introducing the tapered scheme. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><abstract type =“main”xml：lang =“en”> <标题类型=“main”>抽象</ title> >本工作提出了一种用于扩展反射阵列（RA）天线的带宽的新方法。在逐渐阻抗匹配原理的基础上，可以有效地加宽传统电介质RA的窄阻抗。多层元件可以通过适当地选择钻孔通孔的不同层中的不同直径来实现与自由空间的阻抗匹配。此外，具有不同直径的一系列空气通孔改变谐振频率并在彼此之间部分重叠的带宽，从而导致带宽的增宽。为了验证宽带RA天线设计，模拟，制造和测量直径为96Ωmm的圆形RA原型。测量的RA显示出1-DB增益带宽为18.4％。获得的峰值增益为25.18dBi，最大孔径效率为52.18％。显着的实验性能改善证实，通过引入锥形方案可以有效地扩大带宽。</ p> </摘要> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" >著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-24977/'>《Microwave and optical technology letters》</a> <b style="margin: 0 2px;">|</b><span>2019年第12期</span><b style="margin: 0 2px;">|</b><span>共7页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Xi Baokun&option=202" target="_blank" rel="nofollow">Xi Baokun;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Xue Qianzhong&option=202" target="_blank" rel="nofollow">Xue Qianzhong;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Cai Yang&option=202" target="_blank" rel="nofollow">Cai Yang;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Wang Yong&option=202" target="_blank" rel="nofollow">Wang Yong;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Yang Shaopeng&option=202" target="_blank" rel="nofollow">Yang Shaopeng;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Zhang Rui&option=202" target="_blank" rel="nofollow">Zhang Rui;</a> </p> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zkzz" style="display: none;">展开▼</span> </div> </li> <li> <div style="display: flex;"> <span class="lefttit">作者单位</span> <div style="position: relative;margin-left: 3px;max-width: 639px;"> <div class="threelineshidden zhankaihshouqi" id="fOrgthree"> <p>University of Chinese Academy of SciencesBeijing China;</p> <p>University of Chinese Academy of SciencesBeijing China;</p> <p>School of OptoelectronicsSpace Engineering UniversityBeijing China;</p> <p>University of Chinese Academy of SciencesBeijing China;</p> <p>University of Chinese Academy of SciencesBeijing China;</p> <p>Key Laboratory of Science and Technology on High Power Microwave Sources and TechnologiesInstitute of Electronics Chinese Academy of ScienceBeijing China;</p> </div> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zhdw" style="display: none;">展开▼</span> </div> </div> </li> <li > <span class="lefttit">收录信息</span> <span style="width: 86%;vertical-align: text-top;display: inline-block;"></span> </li> <li> <span class="lefttit">原文格式</span> <span>PDF</span> </li> <li> <span class="lefttit">正文语种</span> <span>eng</span> </li> <li> <span class="lefttit">中图分类</span> <span><a href="https://www.zhangqiaokeyan.com/clc/1165.html" title="光学">光学;</a></span> </li> <li class="antistop"> <span class="lefttit">关键词</span> <p style="width: 86%;vertical-align: text-top;"> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=air‐vias&option=203" rel="nofollow">air‐vias;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=broadband&option=203" rel="nofollow">broadband;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=gradual impedance matching&option=203" rel="nofollow">gradual impedance matching;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=reflectarray&option=203" rel="nofollow">reflectarray;</a> </p> <div class="translation"> 机译：空调;宽带;逐渐阻抗匹配;反射阵列;
