摘要

Abstract >In this article, a new method is presented for designing frequency wideband unit cell to use in frequency selective surfaces (FSSs). A double slot square loop (DSSL), which has 2 resonant frequencies, is selected as a primary FSS unit cell and its frequency bandwidth is increased with the proposed method. The effect of the applied innovation on frequency response of DSSL unit cell is investigated by equivalent circuit presented in this paper. Simulated frequency response of the designed unit cell shows that frequency bandwidth of this unit cell increases in comparison with that of primary unit cell. A FSS structure with the designed unit cell is fabricated and its measured return loss confirms that, the frequency bandwidth of the proposed structure is about 50% in X‐band. In addition, frequency response of this FSS structure is stable during 45 degree angle deviation of the incident wave from normal axis of the FSS surface. High frequency bandwidth, low fabrication complexity and stable angular response are the favorable characteristics of the proposed FSS structure which make it suitable for using in microwave filters. </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 XMLNS =“http://www.wiley.com/namespaces/wiley”type =“main”xml：lang =“en” <标题类型=“main”>抽象</ title> 在本文中，提出了一种用于设计用于频率选择表面（FSS）的频率宽带单元单元的新方法。选择具有2个谐振频率的双槽方环（DSSL）作为主FSS单元单元，并且通过所提出的方法增加其频率带宽。本文提出的等效电路研究了应用创新对DSSL单元电池频率响应的影响。设计单元单元的模拟频率响应表明，与主单元小区的相比，该单元电池的频率带宽增加。制造具有设计单元电池的FSS结构，其测量的回波损耗确认，所提出的结构的频率带宽在X波段中约为50％。另外，在来自FSS表面的正常轴的入射波的45度角偏差期间，该FSS结构的频率响应是稳定的。高频带宽，低制造复杂性和稳定的角度响应是所提出的FSS结构的有利特性，这使得适用于微波过滤器。</ 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>2018年第9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=Rahzaani Mahdiye&option=202" target="_blank" rel="nofollow">Rahzaani Mahdiye;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Dadashzadeh Gholamreza&option=202" target="_blank" rel="nofollow">Dadashzadeh Gholamreza;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Khorshidi Mohammadreza&option=202" target="_blank" rel="nofollow">Khorshidi Mohammadreza;</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>Electrical &</p> <p>Electronic Engineering DepartmentShahed UniversityTehran Iran;</p> <p>Electrical &</p> <p>Electronic Engineering DepartmentShahed UniversityTehran Iran;</p> <p>Electrical &</p> <p>Electronic Engineering DepartmentShahed UniversityTehran Iran;</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=frequency selective surface&option=203" rel="nofollow">frequency selective surface;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=1 layer&option=203" rel="nofollow">1 layer;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=resonant frequency&option=203" rel="nofollow">resonant frequency;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=wideband unit cell&option=203" rel="nofollow">wideband unit cell;</a> </p> <div class="translation"> 机译：频率选择性表面;1层;谐振频率;宽带单元电池;
