Abstract: Provided is a method of manufacturing porous metal oxide, the method including: preparing a metal-organic framework (MOF) wherein an ion of a metal to be used as a catalyst is linked to an organic ligand; impregnating the MOF with a precursor solution of metal oxide to be manufactured; and thermally treating the metal oxide precursor solution-impregnated MOF to remove the organic ligand. The inventive method of manufacturing porous metal oxide involves the impregnation of a metal oxide precursor solution in a MOF wherein metal ions are uniformly linked to organic ligands and the thermal treatment (calcination) of the metal oxide precursor solution-impregnated MOF to remove the organic ligands.

Abstract: Provided are a distributed analog phase shifter and a method of manufacturing the same, which reduce a change in a characteristic impedance while changing a phase velocity with respect to an applied voltage. In the distributed analog phase shifter, a coplanar waveguide (CPW) is formed in a line form on a substrate. A plurality of ferroelectric capacitors is periodically loaded to the CPW. The ferroelectric capacitors include a ferroelectric film in a pattern form and defines the ferroelectric film affected by the applied voltage within an area of the ferroelectric capacitors. Accordingly, the change in the phase velocity with respect to the applied voltage is maintained without the change of the CPW characteristic and a return loss characteristic and a total insertion loss are improved since a total dielectric loss of the ferroelectric film is decreased.
