Measured Response Parameters of a Proposed Ultra-Wideband Directional Coupler

A 5.5 KB Excel file by Shrawan K. Patel, last updated in May 2026, contains measured, simulated, and calculated performance data for a novel three-section ultra-wideband directional coupler. The proposed design demonstrates an explicit improvement of approximately 1.2 dB in coupling compared to conventional multi-section couplers. Experimental results confirm the coupler achieves an ultra-wideband response from 0.75 GHz to 3.75 GHz with 8.3 ± 1.4 dB coupling ripple.

Use Cases

• Benchmarking coupling and directivity performance of novel coupler designs based on the reported S-parameter data.
• Validating electromagnetic simulation models against measured experimental results for ultra-wideband components.
• Analyzing the relationship between circuit size (0.067λ₀²) and performance metrics like return loss and isolation.
• Designing multi-section couplers for different bandwidths and couplings using the described transmission line-based approach.

Strengths

• Data includes calculated, simulated, and measured responses, providing a multi-faceted validation of the design.
• Specific performance metrics are provided, including coupling of 7.6-8.3 dB, bandwidths of 104-133%, return loss >16 dB, and directivity >30 dB.
• The dataset is associated with a clear research contribution aligning with SDG 9: Industry, Innovation and Infrastructure.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for statistical analysis.
• The dataset is very small (5.5 KB), indicating a limited scope focused on a single prototype's parameters.
