Antenna Performance Analyzer
Derive antenna optimization strategies from simulation data
What You Can Do
Upload or paste antenna simulation results, and Claude analyzes electrical characteristics to identify performance bottlenecks and recommend targeted optimizations. You get actionable design changes for gain improvement, impedance matching, radiation pattern refinement, and bandwidth expansion. The skill interprets industry-standard formats and translates complex electromagnetic data into engineering insights.
Features
Extract directivity and realized gain metrics, identify frequency-dependent gain variations, and recommend geometric adjustments to maximize radiation efficiency
Analyze S-parameters and return loss across frequency bands, pinpoint impedance discontinuities, and suggest matching network topologies or geometry modifications
Assess 2D and 3D far-field patterns for sidelobe levels, null steering, and main lobe directivity, then propose element repositioning or feed adjustments
Identify frequency-dependent performance limits, quantify impedance bandwidth and gain flatness, and recommend scaling or tuning strategies
Compare multiple antenna designs side-by-side across gain, efficiency, pattern, and bandwidth metrics to highlight trade-offs and guide design selection
Analyze element-to-element coupling effects in arrays, quantify coupling coefficients, and recommend spacing or decoupling network solutions
Prioritize competing objectives (gain vs. size, bandwidth vs. impedance match) and generate Pareto-optimal design recommendations
Example Output
Input: S-parameters and gain data from a 5 GHz patch antenna simulation.
Output:
- Gain is 6.2 dBi but drops 1.8 dB at band edges (4.8-5.2 GHz). Primary cause: impedance mismatch worsens at frequencies away from center.
- Impedance varies from 35 ohms at 4.8 GHz to 65 ohms at 5.2 GHz. Add a quarter-wave transformer or capacitive stub to flatten to 50 ohms across band.
- Sidelobe level at 5 GHz is -10 dB. Recommend reducing ground plane size by 5% or adding parasitic elements to suppress sidelobe.
- Estimated improvement: +1.2 dB gain flatness and -3 dB sidelobe reduction after implementing stub and ground plane adjustment.
Another example: Array mutual coupling analysis shows 12 dB isolation degradation between adjacent dipoles at 2.4 GHz. Recommend 0.4-wavelength spacing (instead of 0.3) or a resistive isolation network on the feedline.
