Title:
MICROSTRIP STRUCTURE-BASED SUBMINIATURE ATOMIC FREQUENCY STANDARD MICROWAVE CAVITY
Document Type and Number:
WIPO Patent Application WO/2022/148210
Kind Code:
A1
Abstract:
Disclosed is a microstrip structure-based subminiature atomic frequency standard microwave cavity, comprising a cavity body. One end of the cavity body is a light outlet; the other end is a light inlet. A line groove is provided in the circumferential direction on the outer surface of the cavity body. A C field coil is wound in the line groove. The light outlet of the cavity body is provided with an end cover. The light inlet of the cavity body is provided with a bottom cover. The bottom cover is provided thereon with a light inlet. An atomic bulb is provided within the cavity body. A microstrip substrate is provided within the cavity body. The microstrip substrate comprises a dielectric substrate and a metal conductor provided on the dielectric substrate. The dielectric substrate is bonded to the inner wall of the cavity body. The metal conductor faces the atomic bulb. The present invention has the advantages of being easy to process and simple to assemble, having a great field distribution, and being compact and inexpensive, and is applicable in the batch production of high-performance subminiature atomic frequency standards.
