Abstract > A circularly polarized antenna is realized using a discontinuous ring dipole. With the introduction of p‐i‐n diodes, it has been possible to achieve polarization reconfigurability in the antenna. The antenna is fed by a tapered feed line, which also acts as a balun and biasing structure. The sense of rotation of the electric field vector (left‐hand or right‐hand) can be controlled by switching the states of the diodes. An equivalent circuit of the antenna is proposed, which has been used to compute the input reflection coefficient of the antenna. The performance of the antenna is verified by comparing the simulated results with the measured results. It has been observed that the antenna has 8.56% overlapping CP bandwidth (a common bandwidth for | S 11|?≤??10 dB and axial ratio, AR ≤3 dB) from 5.03to 5.48?GHz. A measured gain of 3.61?dBic is obtained for all polarization states. The proposed antenna can be used for the 5.2 GHz Wi‐Fi application. </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> > 使用不连续的环偶极器实现圆偏振天线。随着P-I-N二极管的引入，可以在天线中实现极化重新配置性。天线由锥形进料管线供给，该馈电线也用作Balan和偏置结构。可以通过切换二极管的状态来控制电场矢量（左手或右手）的旋转感。提出了天线的等效电路，其已经用于计算天线的输入反射系数。通过将模拟结果与测量结果进行比较来验证天线的性能。已经观察到，天线具有8.56％的重叠CP带宽（常见带宽| s </ i> 11 |≤α≤10dB和轴向比，AR≤3dB）从5.03〜5.48？GHz。为所有偏振态获得3.61〜dbic的测量增益。所提出的天线可用于5.2GHz Wi-Fi应用。 </ 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>2020年第1期</span><b style="margin: 0 2px;">|</b><span>共8页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> </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"> </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=circular polarization&option=203" rel="nofollow">circular polarization;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=dipole antenna&option=203" rel="nofollow">dipole antenna;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=polarization reconfigurable&option=203" rel="nofollow">polarization reconfigurable;</a> </p> <div class="translation"> 机译：圆极化;偶极天线;偏振可重新配置;
