Abstract: In this study, a 38 GHz millimeter wave Yagi antenna was designed and fabricated on a chip using a 0.18 μm CMOS process. The radiation performance of the antenna is improved by using a Yagi antenna with end-fire. The proposed antenna chip measures the reflection coefficient at less than −10 dB over a bandwidth range from 36.6 to 39.8 GHz, covering the 5G n260 band. The CMOS antenna chip has a size of 1.2×1.2 mm2. This study also proposes a solution for the easy measurement of the radiation characteristics to verify the performance in millimeter wave applications. For this purpose, the chip antenna uses bonding wire technology and is verified in a millimeter wave test system. Finally, the simulation and measurement results of the antenna pattern of the bondline technique yield similar radiation patterns.
