摘要

Abstract >An ultra‐wideband antenna is suggested, simulated, and fabricated for ground penetrating radar (GPR) and landmine detection applications. The reported design has wideband, high gain, and high directivity. The new configuration achieves unidirectional radiation characteristics maintaining circularly polarized (CP) radiation characteristics. The whole configuration is optimized using the particle swarm optimization algorithm to achieve the optimal bandwidth, gain, and axial ratio (AR). The performance of the overall geometrical design is analyzed in terms of bandwidth, gain, directivity, and AR. The proposed antenna offers a gain of 2.66?dB in free space, which is enhanced to 8.86 by using an artificial magnetic conductor. The measured results show that the proposed configuration offers ?10 dB return loss bandwidth of 540?MHz over the frequency range (0.8‐1.34?GHz) with ~50.5% operational bandwidth and 3‐dB AR bandwidth of 295?MHz for the frequency range (0.97‐1.265?GHz) with an approximate percentage of 26.4%. Furthermore, the maximum gain over the CP‐operated bandwidth close to 8.86?dB, at frequency 1.05?GHz, is obtained. It is anticipated that this antenna is suitable for GPR applications as well as for employment in landmine detection. </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> <P>一种超宽带天线建议，模拟，以及用于地面穿透雷达（GPR）和地雷探测应用制造。报告的设计具有宽频带，高增益和高方向性。新的配置实现单向辐射特性保持圆极化（CP）的辐射特性。整体结构是使用粒子群优化算法，以实现最佳的带宽，增益，和轴比（AR）进行了优化。整体几何设计的性能在带宽，增益，方向性，和AR方面进行了分析。所提出的天线提供的2.66？分贝在自由空间中的增益，其是通过使用人工磁导体增强8.86。测量结果表明，所提出的配置提供的10分贝的540回损带宽？兆赫的频率范围内（0.8-1.34？千兆赫）以〜50.5％工作带宽和295的3dB带宽AR？兆赫的频率范围内（0.97-1.265？GHz）的26.4％，所占的大致比例。此外，最大增益在CP-操作带宽接近8.86？分贝，在频率1.05？GHz的，被获得。可以预料，这种天线是适合于GPR应用以及用于在地雷探测工作。</ 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12期</span><b style="margin: 0 2px;">|</b><span>共10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=Elsaid Mohamed&option=202" target="_blank" rel="nofollow">Elsaid Mohamed;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Mahmoud Korany R.&option=202" target="_blank" rel="nofollow">Mahmoud Korany R.;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Hussein Mohamed&option=202" target="_blank" rel="nofollow">Hussein Mohamed;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Hameed Mohamed F.
