| description | Abstract In this article an 8-port annular ring-shaped MIMO antenna for 5G and 5G advanced applications is presented. An annular ring on the radiating plane and novel isolator structure on the ground plane are etched over a Rogers RT/Duorid (5870 tm) substrate to achieve high performance antenna for mm wave applications. A systematic study is performed, and an optimized single port antenna (Design-4) is selected among Designs (1-4). The intended 8-port MIMO antenna resonates at 36.4 GHz and exhibits 6.1 GHz (34.2-40.3 GHz) wide bandwidth $$|S_{11}| < -10 \, \text {dB}$$ and 40 dB high isolation level. The proposed antenna covers a complete band of 5G NR-n260 which supports time division duplexing (TDD) mode. Moreover, a unique design of suggested antenna attains a high-level gain of 8.3 dB at 39 GHz and more than 85.2 % radiation efficiency. MIMO characteristics such as ECC, TARC, MEG and CCL are studied and found them in acceptable limit. Additionally, an approach toward massive antenna with 16-port for mmWave applications is also demonstrated. The proposed 16-port massive antenna with more than 22 dB isolation exhibits two bands: first band in 30-33 GHz for ports P9-P16 and second band in 33.5-40.9 GHz for ports P1-P8. A prototype of suggested 8-port antenna is fabricated, tested and validated and found it in close agreement of simulated results. |
