    The invention covers transition devices between a coaxial line and a wave-guide. The central core of the coaxial line enters a transverse partial partition in the wave-guide through an opening in it. The core continues in the wave-guide at the level of the partial partition and promotes the passage from an odd TEM type mode to an even, type TE 10, mode and vice versa.

    (54) COAXIAL-WAVEGNATED TRANSITION
    the conductor is prevented by excitation in the waveguide section by a wolf of the axis type. It is possible only the expansion of open odd waves, but the dimensions of the waveguide segment are such that only waves of the main type can exist in it.
    The combination of an odd TEM wave of a coaxial line with an even wave is achieved due to the decentering of the axis of the coaxial line with respect to the waveguide axis. However, this simjutri does not allow for sufficient excitation and, in addition, it is difficult to achieve consistency of full resistance of segment 3 of the coaxial line and segment 1 of the waveguide due to the fact that CTOpOHbif has different wave resistances and, on the other hand, a low efficiency factor zi meladu waves with even and odd distribution.
    The connection is enhanced by a quarter-wave plot. 6, adjacent to the segment of a coaxial line located in depth with respect to the erasure 7. This quarter-wave section can be formed by extending the waveguide section beyond the wall 7, above the segment of the coaxial line and using the latter centering. In this case, the section of the coaxial line section is smaller than the section of the waveguide section. When fitting such a transition, it is easy to change a number of parameters, such as the length of the exciter element 4 entering the waveguide, the length or height of the quarter-wave section 6,

    The presence of asigu- terry at the –level of the transition entails the occurrence of at least locally even and odd waves. Outside the junction, waves of one type can continue to exist even a wave of type TE, jQ in a waveguide segment, if a waveguide segment is rectangular, CGU, if a waveguide segment is steep, and an odd TEM type wave in a coaxial line.
    There can be two types of waves in the transcode, even and odd, in the extended zone. In FIG. 2 shows that the asymmetry of the field distribution is maintained over the continuation of the internal
    it is the conductor of the segment 3 coaxial lines. This can be explained as a superposition of the odd type of waves shown in Fig. 3 and the even type of the waves shown in Figs. 4. This superposition exists on the line segment formed by the outer conductor, corresponding to the walls of the waveguide section 1, and the inner conductor, corresponding to the continuation of the inner conductor of the 3 segment of the coaxial line.
    Thus, the transition has two zones of connection of different types of waves. One zone, in the P-plane., Shown in FIG. 2, corresponds to the wall .7, i.e., the transmission of the TEM wave existing in the coaxial line into an intermediate segment, B which coexists with even and odd waves, and at the same time this zone corresponds to the connection with the quarter-wave section 6. Other zone - the plane P corresponds to the transition of the intermediate segment to the waveguide segment.
