Antenna pattern measurements: UWB impulse and multifrequency signals comparison




antenna pattern, UWB, impulse, Fourier transform


This paper describes some aspects of wideband (or ultrawideband) measurements of characteristics of antennas which does not require expensive anechoic chambers. The idea of the method is based on exciting the antenna under test by very short impulse which spectrum covers the band of interest and on analysis of spectra of the radiated signals. Reliability of the method is proved by comparison of simulated and measured results of antenna pattern investigations.
