A Compact High-Performance Patch Antenna Array for 60-GHz Applications

In this letter, a compact and high-performance patch antenna array is developed for 60-GHz applications. The method to enhance both the gain and the frequency bandwidth of the antenna array simultaneously by using a parallel-series feed network together with the differential feeding technique is studied thoroughly. The tested antenna array achieves operation bandwidth ( ) from 55 to 68 GHz, which covers worldwide 60-GHz unlicensed band of 57-66 GHz, with peak gain of 12.8-15.6 dBi. The measured -3-dB beamwidths at 61.5 GHz are around ±13° in E-plane and ±15° in H-plane, respectively. The designed high-gain antenna array has a compact size of only 20 ×14 mm2 excluding the connector footprint for test.
