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).

Description

technical field [0001] The invention relates to a millimeter wave and microwave device, in particular to a half-mode substrate integrated waveguide 180-degree three-decibel directional coupler. Background technique [0002] In the existing millimeter-wave and microwave devices, the directional coupler that can achieve 180-degree output phase difference is usually in the form of a microstrip ring bridge and an E-plane waveguide; Better, but the processing is difficult and costly. In recent years, although the 180-degree three-dB directional coupler of the substrate integrated waveguide (SIW) realized by the printed circuit board (PCB) process has excellent performance, as a waveguide structure, the substrate integrated waveguide (SIW) can only meet a certain width. Therefore, the size of the device designed by using substrate integrated waveguide (SIW) and working in the microwave low frequency band is relatively considerable. Therefore, it is of great practical significanc...
