Angle-dependent pulse distortion in UWB radiation and its impact on UWB impulse communications

Abstract

The bit-error-rate of an ultra-wideband (UWB) impulse communication system may vary significantly with respect to communication direction due to angle-dependent pulse distortion in UWB radiation. Simulations of rectangular aperture radiation show that an impulse communication system with uniform aperture electric field excitation suffers more than that with Gaussian aperture field excitation.
