Joint frequency- and time-domain characterization of planar log-periodic antennas

A framework for joint frequency and time domain characterization of planar log-periodic antennas for ultra-wideband systems is established. Effects of antenna's geometrical parameters on time- and frequency- domain performances are discussed and relevant conclusions regarding a low-dispersion log-periodic antenna with acceptable frequency-domain performance are presented. Analysis is performed using method of moments (MoM) as implemented in FEKO.
