摘要

Abstract >A new mixed‐coupled quint‐wideband ASIR bandpass filter with low insertion loss and compact size is proposed: spiral and open‐loop coupled structures realize fundamental mode coupling and enhance another four spurious modes with optimum insertion loss. The fundamental frequency and four spurious frequencies are located at 1.275?GHz with fractional bandwidth (FBW) of 38.4%, 3.225?GHz with FBW of 38.4%, 5.875?GHz with FBW of 12.1%, 7.515?GHz with FBW of 13.7%, 9.74?GHz with FBW of 4.3%. The filter is suitable for multiple applications including GPS, Wi‐Fi and IEEE 802.11a, and partially for IEEE 802.16. The quint‐wideband filter has a performance superior to its currently proposed quint‐wideband counterparts. </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> 提出了一种具有低插入损耗和紧凑尺寸的新的混合耦合Quint-宽带ASIL带通滤波器：螺旋和开环耦合结构实现基本模式耦合，并增强另外四种杂散模式，具有最佳的插入损耗。基本频率和四个杂散频率位于1.275？GHz，分数带宽（FBW）为38.4％，3.225？GHz，FBW为38.4％，5.875个，5.875个GHz，FBW为12.1％，7.515？GHz，其中FBW为13.7％， 9.74？GHz，FBW为4.3％。该滤波器适用于包括GPS，Wi-Fi和IEEE 802.11a的多个应用，并且部分用于IEEE 802.16。 Quint-宽带过滤器具有优于其当前提出的Quint-宽带对应物的性能。</ 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5期</span><b style="margin: 0 2px;">|</b><span>共4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=Al‐Yasir Yasir I.
