Abstract:
This work proposes a small dual-band (2.4 GHz and 4.89 GHz bands) 3D beamforming Multiple-Input Multiple-Output (MIMO) antenna for emerging size-constrained Internet of Things (IoT) applications. The performance is realized via digital beamforming in a structure sized only 51.5 mm in diameter (smaller than half wavelength at 2.4 GHz). At the 2.4
GHz band, the antenna realizes an isolation > 30 dB, and the Envelope Correlation Coefficient (ECC) is < 0.0003), with a
bi-directional beamforming capability in the azimuth plane and unidirectional beamforming across the elevation plane. At the
4.89 GHz band, the isolation is > 19 dB, and the ECC< 0.0047, while unidirectional beamforming is achieved in both the azimuth and elevation planes.
