建立了几个先进的测量装置来表征由微电子探头馈电的毫米波(毫米波)天线。为了评估这些设置本身，通常需要两个或更多高成本的天线样本来进行几次耗时的校准。提出了一种用于快速评估的低成本喇叭阵列，对其进行了理论分析和实验验证。这种喇叭阵列同时辐射在末端和宽边，因此可以用来代替两个独立的样本，如贴片和八木天线。此外，这种喇叭阵列具有波纹图案，带有一系列精确可控的零点，用于灵敏度测量和直接比较以进行评估。采用基片集成波导结构，在单层印制电路板上制作了毫米波喇叭阵列，具有制作简单、成本低的特点。仿真和测量的良好一致性表明，所提出的喇叭阵列极大地促进了对探头馈电天线测量装置的快速和低成本的评估。
Several advanced measurement setups are built up to characterise millimetre‐wave (mmWave) antennas fed by microelectronic probes. To evaluate these setups themselves, two or more high‐cost antenna samples are conventionally required for several time‐consuming calibrations. A low‐cost horn array for fast evaluation is proposed, theoretically analysed, and experimentally validated. This horn array simultaneously radiates at end‐fire and broad side, and therefore can be used to replace two standalone samples such as patch and Yagi antennas. Moreover, this horn array features rippled pattern with a precisely‐controllable series of nulls for sensitivity measurement and straightforward comparison for evaluation. By using the substrate integrated waveguide structure, a mmWave horn array is fabricated in a single‐layer printed circuit board to feature easy fabrication and low cost. Good agreement between simulation and measurement shows that, the proposed horn array significantly facilitate a fast and low‐cost evaluation of the probe‐fed antenna measurement setup.
