摘要
该文将磁电偶极子天线作为辐射阵子,并应用一种共面波导馈电网络,研究并设计了一种新型4×4毫米波天线阵列。这种设计不仅具有很宽的阻抗带宽和增益带宽,而且价格低廉易于生产。仿真和测试结果表明,此天线阵列的相对阻抗带宽为54.5%,3 dB增益带宽为37.1%,在工作频带内（40.2-70.0 GHz）,最大增益为18.1 dBi。而基于其他技术设计的4×4毫米波天线阵列（如微带天线、偶极子天线）工作频带宽度一般在20%左右,增益一般在16-17 dBi。所以该文提出的天线阵列设计具有明显的优势。另外,仿真设计结果和实测的电参数数据有较好的一致性。
This paper presents a new 4×4 millimeter-wave antenna array, which adopts the magneto-electric dipole as the radiating element and a type of coplanar waveguide feed network to excite the array. This design not only provides very wide impedance and gain bandwidths, but also has features of low cost and ease in fabrication. The simulated and measured results reveal that this array exhibits a wide impedance bandwidth of 54.5% and a wide 3 dB gain bandwidth of 37.1%. Over the operating frequency band（40.2-70.0 GHz）, the maximum gain is 18.1 dBi. However, other 4×4 millimeter-wave antenna arrays, designed based on microstrip patch antenna or electric dipole antenna, have the operating bandwidth of about 20% and the gain of 16-17 dBi. Hence, the proposed antenna has an obvious advantage. In addition, the simulated and measured results have a good agreement.
