| 13655 | 提出了一款宽频带高增益的圆极化毫米波天线。 | This paper presents a design of a wideband and high gain circularly polarized (CP) antenna for millimeter-wave applications. |
| 13656 | 该天线由一个半球形的介质透镜圆顶以及一个圆柱形极化器结合而成, 将传统的扩展半球介质透镜与介质极化器融合在一起, 既能将线极化波转化成圆极化波 (反之亦然) , 又能有效提高天线的增益。 | The proposed lens consists of a hemispherical lens and a cylindrical polarizer, which integrate a dielectric polarizer with a dielectric hemispherical lens, and can transfer an incident wave from linear to circular polarization. |
| 13657 | 该设计与传统的级联结构 (透镜级联极化器) 不同, 它能够用一个器件同时实现两个器件的功能, 并且能大大减小系统的体积, 降低插入损耗, 减少生产成本。 | The proposed CP lens is different from the cascaded design of a polarizer and a lens.It can achieve dual function by using single device. Moreover, it can decrease the profile of the extended hemispherical lens, and decrease the insertion loss and the cost of the antenna as well. |

| 13659 | 经过验证, 该天线的阻抗带宽能达到38%, 轴比带宽为36%, 圆极化增益达到22 dBic。 | This antenna can achieve a wide impedance bandwidth of 38% and a wide axial ratio (AR) bandwidth of 36%, and its gain can reach 22 dBic. |
| 13660 | 均匀规则阵列天线的副瓣电平较差, 且波束宽度较宽, 不太适合于一维高精度相控阵雷达系统.针对这些要求, 提出了一种基于串联馈电网络结构的非规则天线阵列。 | The uniform regular array antenna has poor sidelobe level and wide beamwidth, which is not suitable for demanding one-dimensional phased array radar systems. In response to these requirements, an irregular antenna array based on a series-fed network structure is proposed in this paper. |
| 13661 | 该阵列采用串馈方式, 结合带空腔的微波多层板技术, 通过带状线缝隙耦合方式, 避免了背向辐射, 同时获得宽带特性。 | The array takes a series feed method, combined with a microwave multilayer board technology with a hollow cavity, to avoid back radiation and obtain broadband characteristics simultaneously through a stripline slot coupling method. |
| 13662 | 该阵列采用遗传算法对阵列进行优化, 获得低于-18dB的理论副瓣电平, 同时相比均匀规则阵而言, 波束宽度仅有0.2°的拓宽。 | The array is optimized using agenetic algorithm to obtain a theoretical side lobe level below -18 dB.Compared to a uniform regular array, the beam width is only 0.2°widened. |
| 13663 | 对于20°的波束宽度而言, 该波束宽度扩宽量可以忽略不计。 | Compared with the beam width of 20 degree, the beam width extension can be ignored. |
