The article is devoted to the investigation of matching and radiation characteristics of collinear and cylindrical antenna arrays based on various cutting embodiments from bicone line. In-phase collinear antenna arrays of 6, 9, 12 biconical TEM horns, and collinear arrays of 6 elements in the form of 180-degrees, 120-degrees or 90-degrees of cutting embodiments from bicone line were investigated with using the finite element method. It was shown, that the lower matching frequency of collinear antenna arrays of biconical horns almost linearly increases with the number of array elements, while the growth of cutting angle of biconical element raises slightly lower matching frequency of collinear antenna arrays, and significantly increases gain. The shape of radiation pattern collinear arrays is stable in the working frequency band, and gain linearly increases with the frequency. Also, cylindrical antenna arrays were studied, one of them consists of 4 collinear subarrays of 6 180-degrees elements, while the second - 4 collinear subarrays of 6 90-degrees elements. It was shown, that the coupling of closely spaced collinear subarrays in cylindrical array has a slight effect on matching characteristics and radiation patterns. The investigation confirms that feasibility of overband collinear and cylindrical antenna arrays, i.e. overlapping more than one wave range (the ratio of the upper and the lower frequencies - more 1:10) is shown.
