On the significance of current vector alignment in establishing the resonant frequency of small space-filling wire antennas

Abstract

The effectiveness of antenna geometry in terms of lowering or establishing a specific resonant frequency is considered as a function of the current vector alignment in closely coupled sections of wire. The results and discussion presented expand on a previous work (Best, S.R. and Morrow, J.D., ibid., vol.1, p.112-15, 2002) where it was shown that the current vector alignment in fractal and other small space-filling antennas is significant in establishing the antenna's resonant frequency for a fixed total wire length. A variety of antenna geometries are considered to illustrate the significance and manner in which current vector alignment establishes a small antenna's resonant frequency.
