Δ–­FRACTAL SMALL SIZE SLOTTED ANTENNAS

Abstract

On the basis of Δ–fractals slotted antennas are considered. The calculation data of the input impedance, standing wave ratio (VSWR) and the directivity, obtained by computer simulation, are analyzed. The results of calculations of frequency dependences of the characteristics of fractal elements and linear half-wave slot were compared at different geometrical parameters. There is indicated the possibility of using relatively small size slotted fractal antenna elements in structures having low aerodynamic resistance, including compact low-profile radiators and antenna arrays based on them.
