Abstract

The invention relates to radio engineering. The purpose of the invention is to duplicate the gain and efficiency. The antenna contains a radiating conductor 1, conductors 2 and 3 of the counterweight and a feeding feeder with a 4-point connection. Part of the electromagnetic energy supplied to the antenna propagates along conductor 1, and the other part along conductor 2, whose length is L / 4, where A is the working depth of the wave. Reflecting from the end of conductor 2, the wave is collapsed in phase with the wave propagating along conductor I. This leads to an increase in the radiation power in the main direction. Increasing the height of the suspension conductors 2 and 3 compared with the height of the suspension conductor 1 leads to an increase in the coefficient. gain and efficiency of the antenna without increasing the length and number of conductors 1 and without changing the height of their suspension. 1 hp f-ly.

The invention relates to radio engineering, namely to antenna technology.

The purpose of the invention is to increase the gain and efficiency.

FIG. Figures 1–3 show the traveling wave antenna circuit (ABC) with different configuration of the counterweight conductors.

The traveling wave antenna contains a gain of 4 dB at the receiving conductor 1, conductors 2 and 3 (main and additional) counterweights, feeding the feeder (not shown) with connection point 4.

ABC works as follows.

Part of the electromagnetic energy supplied to the ABC propagates along the radiating conductor 1, and the other part along the conductor 2

leads to an increase in radiation power in the main direction. It was established experimentally that an increase in the height of the suspension of the conductors 2, and 3 of the counterweight leads to an increase in the gain and efficiency of the ABC. This can be explained by the fact that with increasing suspension height the radiation resistance of conductors 2 and 3 of the counterweight increases, and consequently, the power of the electromagnetic wave on them. However, the vertical position of the conductors 2 and 3 of the counterweight is undesirable because the radiation of the parasitic (vertical) floor increases customization.

In order to achieve the greatest positive effect, it is preferable to provide the conductors 2 and 3 of the counterweight with the configuration shown in FIG. 1. However, in this case, the greatest height of the supports is required, which is sometimes unacceptable. FIG. 2 depicts the ABC, most free from this deficiency, the electrical characteristics of which
