Description

2. Symmetric strip vibrator containing strip conductors forming a strip feeder line, V-branching, two stripes, two segments, one of which is half the other length of the other in the strip line, two strip plates, the vibrating shoulders of a vibrator, a flat metal screen, overlapping strip feeder line, Y-branching, strip strip and dielectric layer ,. Placed between a metal screen and strip conductors, characterized in that, in order to improve the alignment of the vibrator with the feeder line in the frequency band, meta; the 1st screen is complemented by a T-shaped metal element symmetrically overlapping portions of the strip plates forming the shoulders of the vibrator.

The difference of the vibrator according to the second variant (Fig. 2) is that it is built on an asymmetrical stripline and, accordingly, does not contain one layer of dielectric 7 with a metal screen 5 located on it.

The vibrator in the first embodiment works as follows.

The excitation from the feeder line 1 through the Y branch 2 and the strip segments 3 in antiphase is transmitted to the strip plates forming the shoulders of the vibrator 4, along which it spreads to the symmetrically located end points of the additional T-shaped metal elements 6, as if by a strip line, shielded by these eletentami; . In places where additional T-shaped metal elements 6 are terminated, this excitation causes common-mode currents. the protruding arms of the vibrator 4, as a result of which it is effectively excited. By varying the length of the horizontal part of the T-shaped metal elements b, which partially overlap the shoulders of the vibrator 4, it is possible to ensure the coordination of the vibrator with the given volynism by the pitakney resistance of the strip line.

The principle of operation of the vibrator according to the second variant is no different from the principle of its operation in the first embodiment.

The effectiveness of the proposed vibrator due to significant; an increase in efficiency in the frequency band as compared to E, which is known due to the improvement of the conditions for matching the vibrator with the feeder line.
