摘要

Abstract > A microstrip antenna array with large space and narrow beamwidth working at 24 GHz is presented in this paper. In some millimeter‐wave radar systems, it is often necessary for transmitting antenna with high gain and narrow beamwidth to avoid interference from other information. According to the theory of antenna array, when the number and spacing of the subarrays and the sidelobe level are given, the half‐power beamwidth can be basically determined. In previous studies, the subarray spacing of the transmitting antenna is usually taken as a dielectric wavelength type="mathematics"> λ <sub>g</sub> . In this paper, under the condition that the number of subarrays is given and no grating lobe is generated, the half power beamwidth is further narrowed by increasing the subarray spacing. The final subarray space of the 12?×?8 antenna array is 11.5?mm, that is, 1.68 dielectric wavelength ( type="mathematics"> λ <sub>g</sub> ), and the half power beamwidth of H‐plane is only 5.5°. The simulated and measured results are presented and discussed. Through processing and testing, it is proved that the antenna array has good performance and can be applied to 24?GHz automotive collision avoidance radar or 24?GHz perimeter security radar. </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> > 本文提出了一个具有大空间和窄波束宽度的微带天线阵列。在一些毫米波雷达系统中，通常需要具有高增益和窄波束宽度的天线，以避免与其他信息的干扰。根据天线阵列的理论，当给出子阵列和侧链级的数量和间隔时，可以基本上确定半功率波束宽度。在先前的研究中，发射天线的子阵列间隔通常被视为介电波长 type =“mathematics”> λ. <sub> g </ sub> </ span> 。在本文中，在给出子阵列的数量并且没有产生光栅叶片的条件下，通过增加子轴间距，进一步缩小半功率波束宽度。 12？×8天线阵列的最终子阵列空间为11.5Ωmm，即1.68介电波长（ type =“mathematics”> λ. <sub> g </ sub> </ span> ），H平面的半功率束宽度仅为5.5°。呈现和讨论了模拟和测量结果。通过加工和测试，证明天线阵列具有良好的性能，可应用于24？GHz汽车碰撞避免雷达或24个？GHz周边安全雷达。 </ 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4期</span><b style="margin: 0 2px;">|</b> <span>共6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=Jia Yongtao&option=202" target="_blank" rel="nofollow">Jia Yongtao;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Liu Ying&option=202" target="_blank" rel="nofollow">Liu Ying;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Zhang Yu&option=202" target="_blank" rel="nofollow">Zhang Yu;</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>Science and Technology on Antenna and Microwave Laboratory Collaborative Innovation Center of Information Sensing and UnderstandingXidian UniversityXi'an China;</p> <p>Science and Technology on Antenna and Microwave Laboratory Collaborative Innovation Center of Information Sensing and UnderstandingXidian UniversityXi'an China;</p> <p>Science and Technology on Antenna and Microwave Laboratory Collaborative Innovation Center of Information Sensing and UnderstandingXidian UniversityXi'an 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=automotive collision avoidance radar&option=203" rel="nofollow">automotive collision avoidance radar;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=half power beamwidth&option=203" rel="nofollow">half power beamwidth;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=large space&option=203" rel="nofollow">large space;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=narrow beamwidth&option=203" rel="nofollow">narrow beamwidth;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=perimeter security radar&option=203" rel="nofollow">perimeter security radar;</a> </p> <div class="translation"> 机译：汽车碰撞避免雷达;半功率束宽度;大空间;窄梁宽;周边安全雷达;
