"A Dataset of Electromagnetic Simulations for a Microstrip Patch Antenna Targeting the 5G NR n78 Band: S11 and Realized Gain"

"We present a dataset of 256 microstrip patch antenna designs with electromagnetic simulation results (S11 reflection coefficients, gain, and realized gain). The designs target the 5G NR n78 band (3.3\u20133.8 GHz) and were generated using maximin Latin Hypercube Sampling across five geometric parameters. The nominal geometry and \u00b120% design-space variation were chosen to produce designs resonating at multiple operating frequencies across n78, enabling coverage of the full band. All designs were simulated over 2\u20135 GHz to capture the complete electromagnetic response around the target band. This dataset is suitable for machine learning and surrogate modeling applications, enabling predictive models for S11 and gain from geometric inputs. The dataset supports an associated manuscript currently under review."
