Abstract. In the paper the structures of the Bragg microwave coax designed on
the base of optical technologies transfer similar to fiber Bragg gratings are discussed.
Methods of its analysis and the results of experimental studies are presented.
Symmetric two-row and three-row structures are firstly described. It is shown
that the Q-factor of the microwave Bragg structure on the design frequency
increases with the order of resonance (at fold change of the structure length and
period of its irregularities) and a number of rows. Approaches and options for
the use of these structures in sensory applications are examined especially for
measuring the temperature and the dielectric permittivity.
Keywords: microwave Bragg
