The waveform of the electric field radiated by an antenna in a UWB system is usually a distorted form of the input pulse applied at the terminals. This distortion can be expressed in terms of the antenna impulse response in the time domain or directional transfer function in the frequency domain. Even for a simplest antenna like a linear dipole, the impulse response can be direction dependent. However, if the antenna's response in different directions are unrelated, modeling of such antennas with other elements of the UWB system can be complicated. Therefore, it is better to design antennas with consistent performance in all the directions of interest as far as possible. As the radiation patterns of UWB antennas can be measured easily, using standard antenna testing methods, it is useful to establish the link between the correlation of far-field waveforms in different directions and the frequency stability of the radiation pattern, when designing antennas with good UWB performance.
