Abstract:
     The invention discloses a semi-graphic base integrated waveguide 180 deg. three-decibel coupler with millimeter-wave and microwave element, which is characterized by the following: the first and second semi-graphic base integrated waveguides (4) and (5) are set on two sides of positive center line of dielectric base (1); the input end (41) and output end (42) are formed on two ends of first semi-graphic base integrated waveguide (4); the separating end (51) and coupling end (52) are set on two ends of second semi-graphic base integrated waveguide (5); a row of metal through-hole (3) is applied by the first and second semi-graphic base integrated waveguide (4) and (5) together as separating band with coupling sew (6); an upper metal notch (44) is set on the opening surface of first semi-graphic base integrated waveguide (4) at upper center of coupling sew (6); a lower metal notch (54) is set on the opening surface of second semi-graphic base integrated waveguide (5) at lower center of coupling sew (6).
