Abstract
Recently the effects of a frequency-dependent phase center on the time domain behavior of an antenna were described with an analytical expression for the antenna impulse response. This relation will be compared to the characteristics of a Logarithmic-Periodic Dipole Array (LPDA) within this paper. Similarities between the impulse response of an LPDA and a moving phase center will be identified. The results indicate that the dispersive behavior of an LPDA is caused by this phase center movement.
