We present a linearly polarized ultrawideband design for millimeter-wave phased array antennas over 17–42 GHz. The design comprises tightly coupled dipoles, integrated with a specific feeding mechanism. The proposed antenna provides a relative bandwidth of 2.7:1 and 2.47:1 with VSWR < 2 for scanning up to 45° in the E- and H-planes, respectively. Several prototypes of $8\times 4$ arrays are fabricated using standard PCB technology. The measurement results of the array prototypes show a good agreement with the simulations in terms of VSWR, radiation pattern, and realized gain.

具有集成馈电的全平面超宽带紧耦合阵列 (FPU-TCA),适用于宽扫描毫米波应用

我们提出了一种用于 17-42 GHz 毫米波相控阵天线的线性极化超宽带设计。该设计包括紧密耦合的偶极子,并与特定的馈电机制集成在一起。建议的天线提供 2.7:1 和 2.47:1 的相对带宽,VSWR < 2,分别用于在 E 和 H 平面中扫描高达 45°。几个原型 $8\乘以4$ 阵列是使用标准 PCB 技术制造的。阵列原型的测量结果表明,在 VSWR、辐射方向图和实现增益方面与仿真结果非常吻合。
