To meet the requirement of ultra-thin rubidium frequency standard, we developed a non-standard rectangular cavity based on the slotted-tube microwave cavity with 12 mm thickness and a field orientation factor of about 0.9. The data set of 87Rb double-resonance signals of the cavity-cell assembly was measured. The results showed that the intrinsic linewidth is about 452 Hz. With the optimized experimental parameters, the cavity-cell assembly has a potential short-term stability of 5.2×10-13τ-1/2 limited by the shot noise.
