The measurement impulse response of UWB antennas in the Time-Domain

Abstract

This paper presents an experimental study, in which Time-Domain pulse technique is used to characterize the performances of an Ultra-Wide Band (UWB) antennas. Pulse with 4.0ns duration is generated, modulated and used to measure the far-field characteristics of printed antennas at 5.25GHz. The proposed method can be used for characterizing Ultra Wide Band antennas in the time domain, especially in a dense multi path environment.
