SU1539871A1 - Symmetring device for solid half-wave vibrator - Google Patents

Abstract

The invention relates to radio engineering. The purpose of the invention is to expand the alignment band and simplify the design. Electromagnetic waves propagating along the coaxial feeder 3, excite currents in the shoulders of the continuous half-wave vibrator 2 and in the parallel loop formed by segment 1 of the conductor. The currents in the left shoulder of the vibrator 2 and segment 1 are in-phase, and in the right shoulder (due to its strong connection with the closely spaced segment 1), the current has a direction opposite to the current in segment 1. This achieves balancing. The reactance of the loop compensates for the imaginary part of the resistance of the vibrator 2. Thus, the extension of the working band of the matching frequency is achieved by selecting the dimensions of segment 1 and vibrator 2 without using a tuning element, which simplifies the design. 1 il.

Description

the current and excite the currents in the conductor in order to expand the matching band forming the continuous shoulders and simplify the design, the dimensions of the half-wave vibrator 2 and the segment of the conductor segment are selected from the corrector conductor 1 forming the parallel lines L (0.52-0 , 75), ny loop. In this case, the currents in the left (see the drawing) shoulder of the continuous half-wave vibrator 2 and the conductor segment 1 are in-phase, and in the right shoulder due to its strong connection with the closely spaced conductor segment 1, the current has the opposite direction to the current cut off
