Chinese smartphone manufacturer Vivo and U.S. semiconductor company Qualcomm have integrated a 5G millimeter wave antenna array into a commercial-sized smartphone and measured its performance over the air, the companies announced.
The design integrates a 28 GHz mmWave antenna array into a cellphone-sized form factor that also uses sub-6 GHz technologies, Qualcomm said in a blog about the Vivo announcement. Qualcomm engineers conducted radiated measurements at Qualcomm’s antenna lab in San Diego to verify the antennas’ performance.
