Abstract

This study investigates the effects of various antenna parameters, such as the substrate material, thickness of the superconducting patch, and operating temperature, on the resonance frequency and surface resistance/reactance of an H-shaped patch antenna printed on a uniaxial anisotropic substrate using a hybrid cavity model and fabricated with superconductor material. This model stands out for its simplified mathematical approach and cost effectiveness. Importantly, the numerical results demonstrate a high level of agreement with the experimental findings reported in the literature, reinforcing the reliability of our study. Additionally, other numerical results demonstrate the impact of the superconductivity materials on the resonant characteristics of the H-shaped compact microstrip antenna.
