| Popis: | Ring antenna arrays find wide application in radio systems of various purpose. However, in many cases it is necessary to use quasi-ring antenna arrays when the emitters are not located in a circle. Such a transition leads to a change in the radiation pattern, i.e. to a shift in its main maximum, an increase in the level of the side lobes, and appearance of two maxima of the radiation pattern. Therefore, to ensure the formation of a directional pattern with specified parameters, it is necessary to correct the amplitude-phase distribution of the quasi-annular antenna array. In this paper, features are considered and an algorithm for the synthesis of the amplitude-phase distribution of a quasi-annular antenna array is developed. The possibilities of preserving the parameters of the directional pattern during the transition from the ring to the quasi-annular antenna array are analyzed. |
