Abstract: ABSTRACT This invention presents a high-performance lampshade micro strip patch antenna engineered for Kaband operation and enhanced using machine learning- assisted optimization. The antenna is designed on an FR-4 substrate and the radiating patch incorporates three stepped slots strategically positioned to induce multi- resonant behavior and improve impedance matching. The design integrates a slotted partial ground plane to suppress surface waves and broaden the impedance bandwidth. Electromagnetic simulations using HFSS show dual-band resonances at 26.38 GHz and 28.63 GHz with return losses of -37.073 dB and -82.723 dB, respectively. The antenna achieves a wide bandwidth of 4.36 GHz, excellent impedance values near 50 Q, and a peak gain of 13.6 dB. A regression-based machine learning framework is employed to predict and optimize return loss (S 11 behavior), with the K-Nearest Neighbours Regressor achieving top performance (MSE = 0.2687, RMSE = 0.5184, MAE = 0.0945, R2 = 0.9934). The integration of ML substantially reduces simulation effort and accelerates iterative optimization. Due to its high gain, wideband characteristics, and ML-driven optimization, the antenna is suitable for 5G/6G systems, satellite communication, automotive radar, avionics, and Ka-band biomedical imaging.
