A slotted-tube microwave cavity with a volume of 11 mL was designed for miniaturized high-performance rubidium atomic frequency standards (RAFS). The magnetic field orientation factor of the cavity was measured to be 0.83. A miniaturized physics package for RAFS was designed based on the dimensions of the cavity, and a desk prototype of RAFS was built. Short-term frequency stability of the miniaturized RAFS built was measured to be better than 2×1012/√τ, suggesting that the microwave cavity can be utilized for construction of RAFS with small size and high performance.
