Enhanced Gain and Isolation Dual-Band Dual-Port MIMO Antenna with Integrated Lens for Millimeter-wave 5G Internet-of-Things Applications
Abstrakt
This paper proposes a dual-band dual-port Multiple Input Multiple Output (MIMO) antenna with enhanced gain and port isolation for 5G millimeter-wave (mm-wave) Internet of Things (IoT) applications. The gain enhancement is achieved using a 3D-printed dielectric lens integrated with the antenna, whereas port isolation is improved using a novel 2D compact metamaterial incorporated between the MIMO elements. The proposed integrated lens MIMO antenna (ILMA) design exhibits lower mutual coupling, low fabrication cost, and higher gain. At the same time, it uses a simple planar antenna feeding technique which features a small footprint compared to larger antenna arrays typically employed for gain enhancement. The overall size of the two-port integrated lens MIMO antenna is 19 × 29 × 13 mm3. The peak gain without dielectric lens is 6.5 dBi and 7.9 dBi at the two operating bands, which is further enhanced with a 3D-printed dielectric lens to 9.5 and 11.4 dBi at 26 GHz and 38 GHz, respectively. The proposed ILMA exhibits high isolation exceeding 30 dB and 22 dB at 26 GHz and 38 GHz. Experimental validation of the ILMA prototype corroborates the relevance of the assumed design approach. Compared to the MIMO antennas reported in the recent literature, the suggested integrated lens MIMO antenna not only offers a higher gain while maintaining a small footprint but also improves the isolation between the radiating elements. These features make the proposed design an attractive choice for mm-wave 5G internet-of-things (IoT) applications.
