CIRCULATOR USING FERRITE DISK ON NON-RADIATIVE MICROSTRIP LINE

摘要

available in the millimeter-wave band of the present invention to syeokyul ferrite disk emulator for non-radiation using a microstrip line relates. ; is preferably a dielectric substrate between the upper and lower conductors with a spacing of less than half the wavelength of the used frequency insertion plate and the input port on the dielectric substrate, to the output port of the cut-off port and a micro-cast sipseon is 120 and are disposed at intervals, each port on each ferrite magnetic material is attached to each of the circular disk on a dielectric substrate top surface and a bottom surface relative to the circular pad of the copper foil to meet in common and, in order to obtain the saturation magnetization of the ferrite disk thereof upper and lower conductive plates by placing permanent magnets on the top and bottom surfaces of the ferromagnetic structure is not affected by changes in external magnetic field. ; The structure than the conventional waveguide type, a ferrite disk on a dielectric substrate above and below the strip line Write a simple structure because the loss of adhesion, easy to manufacture and can be easily mass-produced at low cost. ; These non-radiation microstrip line for syeokyul emulator is available millimeter-wave band in duplexer (duplexer), or Transceivers are applicable to high-capacity circuits for broadband bi-directional communications (transceiver).
