A diamond‐shape stub is proposed to enhance the bandwidth of a resonant type comb‐line array at 60 GHz. For linear polarization, a vertical slit is adopted and its optimal length is determined. Design graphs for the input impedance, quality factor (Q), and the resonant length of a single cell are presented. A simple demonstration is given that the Q of the array could be reduced by designing a stub having a lower Q. A resonant type comb‐line array is designed based on the design graphs. The performance of the proposed array is measured and compared to the conventional and published comb‐line arrays. The proposed array demonstrates a broader bandwidth, while the gain pattern is the same as that of the conventional comb‐line array.

60 GHz带宽增强梳状线阵列的设计

提出了菱形短截线以增强60 GHz谐振型梳状线阵列的带宽。对于线性极化，采用垂直狭缝并确定其最佳长度。给出了输入阻抗，品质因数（Q）和单个电池谐振长度的设计图。一个简单的示范给出的是，Q阵列的可通过设计具有低的存根被减小Q。根据设计图设计谐振型梳状线阵列。测量所提出的阵列的性能，并将其与常规和公开的梳状线阵列进行比较。所提出的阵列展示了更宽的带宽，而增益模式与传统的梳状线阵列相同。
