A 100-M/s 2.6-pJ/pulse Compact UWB Impulse Transmitter based on Antenna-and-Pulse-Generator Codesign

抄録

This work presents a novel concept of antenna-and-pulse-generator codesign for realizing FCC-regulation-compliant IR-UWB transmitters. The method contributes to a compact design that significantly reduces the overall device footprint and energy consumption. A Gaussian mono-pulse generator and a folded-dipole antenna with a bandwidth of 7.8-9.5 GHz are co-optimized, eliminating any matching sections. The energy consumption for each impulse emission is only 2.6 pJ and 100 Mpulse/s operation of the transmitter complies with the FCC mask. The transmitter of this kind shows promise for size-restricted and ultra-low power applications such as medical implants.
