Overview

Demonstrates the performance of a dual-band flexible MIMO antenna in head-mounted devices, indicating its suitability for advanced communication.

Key Points

  • The aim is to develop and evaluate a dual-band flexible MIMO antenna suitable for wearable devices in 5G/6G applications.
  • Designed a dual-band MIMO antenna based on polyimide flexible printed circuit substrate.
  • Characterized antenna performance under bending conditions and evaluated Specific Absorption Rate (SAR) in a human tissue model.
  • Measured impedance matching and isolation characteristics across frequency bands.
  • Antenna shows stable electromagnetic performance under bending conditions.
  • Achieved at least 23.4 dB isolation between two ports.
  • Impedance bandwidth covers 3.42–3.84 GHz and 4.37–7.80 GHz, meeting 5G/6G frequency requirements.
