Measurement of a 60-GHz-Band Digital Beamforming Array Using 4-by-2 Circular Patch

In this paper, a 60-GHz-band dual-polarized digital beamforming array antenna using circular patch is experimentally demonstrated. If two feed pins are used for real usage, we can obtain the 10 dBi beam coverage area of 360 degree in phi and 0 - 60 degree in theta by using the coordinate system shown in Fig. 3. Based on the measurement result, we show that beamforming coverage area can be expanded by the synthesis of dual-polarized configuration with beam switch operation.
