"Microstrip Antenna Dataset for S-Parameters and 2-D Radiation Patterns"

"The dataset contains approximately 190,000 microstrip-antenna samples. Each sample includes S-parameters evaluated at 101 frequency points, together with a 17-dimensional encoded-domain representation of the S-parameters based on a Lorentzian-resonance formulation, as well as 2-D far-field radiation patterns sampled at 11 frequency points. The dataset covers diverse operating conditions spanning 0.5\u201310 GHz and substrate permittivities \u03b5r\u200b\u2208[2,10], and includes S-parameter responses with widely varying resonance amplitudes and quality factors. It is well suited for training antenna performance evaluators and inverse-design networks."
