Characterizing 60 GHz Patch Antenna Segments for Fully Digital Transceiver

In this work, we present the simulation and measurement results of patch antenna elements operating at 60 GHz for future integration with fully digital transceiver. The antennas are fabricated on Rogers 4350B substrate of 168 μm thickness and their radiation patterns are measured both in the anechoic chamber and planar near-field range. In addition, different types of transmission lines are designed and fabricated. Results for both patch antennas and transmission lines show rather good agreement between simulation and measurements. The measured -10dB bandwidth of single element is 1.76 GHz around center frequency of 60.3 GHz. In the future, 1x4 patch antenna array will be integrated with the four channel software-defined radio.
