摘要

Abstract >This article proposes the design of a 16‐element array antenna with a planar L‐shaped probe for a direction of arrival (DoA) estimation of an unidentified broadband signal. The individual element of the proposed antenna consists of a shorted radiating patch and the planar L‐shaped probe for obtaining the broad matching characteristic, wide beamwidth, and miniaturization. The developed individual elements are adopted to implement a planar 4?×?4 array antenna and to verify beam scanning properties. To obtain the improved signal detection performance of the proposed array antenna, the optimal array spacing of the proposed antenna is determined by calculating a root mean square error (RMSE) and the side lobe level. The results demonstrate that the proposed 4?×?4 array antenna with the optimal array spacing is suitable for detecting the unidentified signals with low RMSEs in a given signal detection environment. </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> 本文提出了一种具有平面L形探针的16元件阵列天线的设计，用于未认定的宽带信号的到达方向（DOA）估计。所提出的天线的各个元件包括短路辐射贴片和平面L形探针，用于获得广泛的匹配特性，宽波束和小型化。采用开发的各个元件来实现平面4？×4阵列天线并验证波束扫描属性。为了获得所提出的阵列天线的改进的信号检测性能，通过计算根均线误差（RMSE）和侧瓣级来确定所提出的天线的最佳阵列间隔。结果表明，所提出的4？×4×4阵列天线具有最佳阵列间距，适用于在给定的信号检测环境中检测低RMS的未识别信号。</ 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10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"> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Jang Doyoung&option=202" target="_blank" rel="nofollow">Jang Doyoung;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Yoo Sungjun&option=202" target="_blank" rel="nofollow">Yoo Sungjun;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Wang Jinchun&option=202" target="_blank" rel="nofollow">Wang Jinchun;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Choo Hosung&option=202" target="_blank" rel="nofollow">Choo Hosung;</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>School of Electronic and Electrical EngineeringHongik UniversitySeoul South Korea;</p> <p>School of Electronic and Electrical EngineeringHongik UniversitySeoul South Korea;</p> <p>Electronics and Telecommunications Research InstituteDaejeon South Korea;</p> <p>School of Electronic and Electrical EngineeringHongik UniversitySeoul South Korea;</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=antennas&option=203" rel="nofollow">antennas;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=array antennas&option=203" rel="nofollow">array antennas;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=broadband antennas&option=203" rel="nofollow">broadband antennas;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=direction finding&option=203" rel="nofollow">direction finding;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=signal detection&option=203" rel="nofollow">signal detection;</a> </p> <div class="translation"> 机译：天线;阵列天线;宽带天线;方向发现;信号检测;
