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.
