Thermal and Mechanical Analysis of Millimeter-Wave Leaky-Wave Antennas

Next-generation 6G and Sub-THz radiators demand micro-scale precision. However, conventional design relies on idealized, infinite-periodic models that fail to account for physical reality. This research quantifies the critical "Gap" where theoretical predictions meet real-world constraints. By evaluating finite aperture truncation, manufacturing tolerances, and conformal bending, we demonstrate how these factors collectively induce beam squint, sidelobe degradation, and impedance mismatch. The goal is to establish a physically grounded, predictive design framework for highly reliable aerospace applications.
