Abstract

The article focuses on the design and simulation-based optimization of a microwave cavity used in active hydrogen masers, which are critical for achieving exceptional frequency stability in satellite navigation systems such as NavIC and the Deep Space Network. It details the cavity’s cylindrical geometry, material selection (aluminium), and vacuum operation to minimize losses and maintain resonance at the hydrogen atom’s hyperfine transition frequency (~1.42 GHz). Using advanced simulation tools like HFSS and Ansys Maxwell, the study evaluates resonant frequencies, quality factor (Q-factor), and dimensional sensitivities, highlighting the importance of precise manufacturing for stable maser performance. The findings support the development of more accurate time sources for space-based navigation and suggest further refinements in fabrication control to enhance stability and reduce frequency deviations.
