摘要

讨论了50:1带宽印刷电路板对数周期偶极子阵列天线的设计细节，用于实际射频干扰测量。进给卡设计优化，避免了需要在对面板上的假电缆来平衡进给电缆结构。计算机模拟和测量了在50 MHz至8 GHz范围内实现的增益和反射系数结果。虽然天线在150兆赫到7.5千兆赫的预期带宽范围内工作得很好，但它可以使用到70兆赫。

A practical 50∶1 bandwidth PCB-LPDA antenna for MeerKAT RFI studies

Design details of a 50:1 bandwidth printed circuit board log periodic dipole array antenna for practical radio frequency interference measurement use are discussed. A feeding tab design optimization is incorporated, which obviates the need for a dummy cable on the opposite board to balance the feed cable structure. Computer simulated and measured realized gain and reflection coefficient results are shown from 50 MHz to 8 GHz. Although the antenna works well over its intended bandwidth of 150 MHz to 7.5 GHz, it can be used down to 70 MHz.
