Abstract

A dispersion of two-arm planar equiangular and Archimedean spiral antennas is investigated. Frequency domain characterization of spiral antennas-based ultra-wideband link is conducted computationally and experimentally. The time domain performance is obtained by post processing frequency domain data using the inverse fast Fourier transform. Effects of source pulse shape and antenna´s geometrical parameters on the dispersive properties of the channel are discussed and relevant conclusions regarding the low-distortion spiral antenna are presented. Finally, a theoretical pre-distortion compensation method based on a frequency-dependent delay removal technique is employed to enhance the performance of spiral antennas as pulse radiators.
