Wideband Shared-Aperture Antenna for Full-Screen 5G Mobile Devices

Blog Article

This paper presents a novel shared-aperture smartphone antenna for sub-6 GHz and millimeter-wave (mmWave) bands.The proposed antenna module muumi lyhty comprises a four-element mmWave patch antenna array integrated into a wideband sub-6 GHz slot antenna.The mmWave antenna covers the frequency band 26.5–29.

5 GHz with isolation over 16 dB, and the sub-6 GHz antenna covers several bands on the frequency range 3.4–6.0 GHz with isolation over 15 dB.The key features in the proposed concept are that a metal part of the sub-6 GHz antenna acts as a ground plane for hand wipes individual packets the mmWave antenna array, and both antennas are located solely on the metal rim enabling a full edge-to-edge screen.

The antenna achieves a high total efficiency of 65–95% and −3 dB beam steering range ±40°.A prototype is manufactured, and measurements verify wideband operation and high isolation in both frequency bands.The four-element multiple-input multiple-output (MIMO) operation with the proposed shared aperture antenna is demonstrated at the sub-6 GHz band.
