Title: Mode coupler
Inventor: OGASA MITSUAKI
IPC: H01P5/18
Filed: 1986-09-30
Abstract: PURPOSE:To shorten the overall length of the titled mode coupler so that it can be used a satellite on-board RF sensor, by determining the dimension of the main waveguide and a sub-waveguide and the interval of coupling holes so that the coupling electromagnetic wave of a specific desired mode is propagated in the same phase in the sub-waveguide, and the coupling electromagnetic wave of a specific unnecessary mode is offset in the opposite phase. CONSTITUTION:In order not to couple a TE21 mode, two coupling holes 13a, 13b are formed, and by setting its interval (l) to l=(3/2)lambda21=2lambda01=lambda10, a TM01 mode is coupled. In this regard, lambda21 is the pipe wavelength of the TE21 mode. The dimension of a main waveguide 11 and a sub-waveguide 12 and the interval (l) of coupling holes 13a, 13b are selected and set so that such a relation is formed. In this way, a mode coupler for coupling a necessary mode, and coupling no unnecessary mode by two coupling holes 13a, 13b can be constituted. Accordingly, the structure becomes small, and also, since the number of pieces of the coupling holes is small, when a mission wave has been propagated to the main waveguide, the influence exerted on its mission wave can be made extremely small.

From the main surface of the single crystal silicon substrate 1, second conductivity type impurity ion is implanted, whose impurity concentration is higher than that of the single crystal silicon substrate, and lower than that of the single crystal silicon film 4a. Thus, a second conductivity type region 5 is formed on the surface part of the substrate 1 on which an aperture part 2 is formed. Since impurity ion is not diffused by heating, the impurity distribution at a P-N junction part can be sharply changed.
