本文介绍了对由矩形波导宽壁上的横向槽馈电的微带天线阵列的测量，该微带天线阵列采用驻波激励，用于平行于轴的线性极化。由波导的横向槽激励的介电基板上的串馈两元件微带天线阵列被用作所提出的阵列的元件，用于抑制由于横向槽引起的栅瓣。本文设计并制造了由六个微带天线组成的原型阵列，这些微带天线由驻波激励矩形波导的宽壁上的三个横向槽馈电。测量结果与HFSS模拟结果一致。测量的辐射方向图表明，所提出的阵列大大减少了由横向槽引起的分级波瓣。测量证实了所提出的阵列设计的有效性。
This paper presents measurement of a microstrip antenna array fed by transverse slots on a broad wall of the rectangular waveguide with standing wave excitation for linear polarization parallel to the axis. A series-fed two-element microstrip antenna array on a dielectric substrate excited by a transverses slot of the waveguide is used as an element of the proposed array for grating lobe suppression due to the transverse slots. In this paper, a prototype array consisting of six microstrip antennas fed by three transverse slots on the broad wall of the rectangular waveguide with standing-wave excitation is designed and fabricated. The measured results are agreed with the simulated ones obtained by HFSS. The measured radiation pattern reveals that grading lobes due to the transverse slots are well reduced by the proposed array. Validity of the design of the proposed array is confirmed by the measurement.
