TRAVELING-WAVE ANTENNA WITH A REDUCED LEVEL OF SIDE LOBES DUE TO VARIABLE PHASE VELOCITY
One of the main parameters that characterize the quality of the antenna side lobe level is that in some cases should be the lowest possible with minimum dimensions of the antenna. The aim of this work is to find a method for reducing the side lobe level at constant mass-dimensional parameters of the...

| description | One of the main parameters that characterize the quality of the antenna side lobe level is that in some cases should be the lowest possible with minimum dimensions of the antenna. The aim of this work is to find a method for reducing the side lobe level at constant mass-dimensional parameters of the antenna. The study has found a link between the distribution function of the deceleration phase velocity along the traveling wave antenna and the level of the side lobe. In particular, it was found that under certain laws of the phase velocity changes along the antenna, the level of the side lobe can be reduced significantly. As a result of numerical analysis of directional antennas traveling wave chart with slow phase velocity varying sinusoidally, revealed a decrease in the level of the first and second side lobes 1.5 ... 3 times as compared with the conventional optimum traveling wave antenna. Despite the reduction in the emission side, directional factor is the same as that of a conventional antenna of a traveling wave with a constant phase velocity of the same length. |
