Optimal Dimensions for a Four-Port MIMO mmWave Antenna Design

A dataset containing optimal dimensions for a four-port multiple-input-multiple-output millimeter-wave antenna designed for 5G FR2 bands n260 and partial-n263. The antenna was fabricated on a flexible Rogers substrate and characterized for S-parameters, far-field results, bending analysis, and Specific Absorption Rate. Key performance metrics include impedance bandwidths of 36.60GHz-39.12GHz and 58.48GHz-61.48GHz, with averaged gains of 6.532dBi and 6.978dBi for the respective bands.

Use Cases

• Optimizing antenna geometry for dual-band mmWave operation based on specified PCB space constraints.
• Analyzing bending performance for conformal applications based on the described 45-degree axis bending tests.
• Evaluating MIMO diversity performance based on metrics like Envelope Correlation Coefficient and Diversity Gain.
• Assessing Specific Absorption Rate for on-body safety compliance based on the provided single-port and MIMO SAR values.

Strengths

• Specific physical dimensions are provided for both single-port (6×8 mm²) and four-port (12×16 mm²) antenna versions.
• Concrete performance metrics are listed, including two distinct impedance bandwidths and averaged gains for each band.
• Detailed MIMO diversity parameters are quantified, such as an Envelope Correlation Coefficient below 2.93×10⁻⁴.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small (5.5 KB), indicating limited scope, likely containing only key design parameters.
