Single Band 5G mmWave Two Port MIMO Antenna with Omnidirectional for High Speed Wireless Applications

Abstract

The research paper reports presents two port multi-input-multi-output (MIMO) antenna were RF Substrate Rogers RTDuroid5880 is used with bell-shaped radiator printed on top plane and rectangular slotted ground with chamfered edges. The antenna is very compact in size with dimensions $24\text{mm}\times 14\text{mm}$. The antenna resonates at 28GHz with −10dB bandwidth of 27.14GHz-29.88GHz. This bandwidth is suitable for 5G 28GHz band for high speed applications useful for Internet-of-Things (IoT) which can be implemented for smart cities. The MIMO antenna provides good isolation and diversity performance. The antenna also offers maximum gain of 4.89dBi with desired radiation pattern. Some of the challenges in deployment of 5G technology is also discussed.
