Antenna-Circuit-Signal Co-Design for UWB Systems

We analyze UWB signal transmission based on combining full-wave EM solutions and equivalent circuits that account for signal dispersion caused by terminal-loaded dipole antennas operating across UWB channels. First, full-wave EM modeling supplies channel numerical transmission functions while their network interpretations provide some useful system-level insight on the collective impact of used antenna geometrical shapes, transmitter-receiver front-end impedances and transmitter driving waveforms. For this, several important performance merits can be considered in frequency domain (FD) and time domain (TD) including energy transmission efficiency, confinement time of pulsed energy, group delay deviation and others. All numerical results are given in a normalized form that makes them scalable to any particular geometry-frequency-time range of interest
