Overview

This design proposes a MIMO antenna for enhanced port isolation and efficiency in wireless systems, indicating improved performance.

Key Points

  • To design a planar dual-frequency MIMO antenna that supports 5G n77/78/79 and WiFi applications while achieving high port isolation.
  • Designed a C-shaped monopole feeding antenna and additional strips for frequency tuning.
  • Implemented a Y-shaped neutral line to enhance isolation between antenna elements.
  • Fabricated on an FR4 substrate measuring 45 × 45 × 1.59 mm3.
  • Achieved −10 dB reflection coefficient bandwidths of 460 MHz (3.37–3.83 GHz) and 1060 MHz (4.79–5.85 GHz).
  • Maintained isolation greater than 15 dB in both frequency bands.
  • Exhibited efficiency of over 47% with an envelop correlation coefficient below 0.02.
