Impulse UWB antenna size reduction due to transmitter-antenna co-design

In this paper, the benefit of a co-design between a modified small-size printed tapered monopole antenna (PTMA) and an impulse ultra wideband transmitter is investigated for the 3.1-10.6 GHz band. A comparison is given between a 50 Omega design and a co-designed version. The simulation results show that with the co-design method the tunable UWB transmitter can reach the bandwidth regulation for a much smaller antenna.
