This paper discusses two antennas monolithically integrated on-chip to be used respectively for wireless powering and UWB transmission of a tag designed and fabricated in 0.18-μm CMOS technology. A multiturn loop-dipole structure with inductive and resistive stubs is chosen for both antennas. Using these on-chip antennas, the chip employs asymmetric communication links: at downlink, the tag captures...
A small size-optimized Printed Tapered Monopole Antenna (PTMA) for UWB application with band-notched characteristic is designed and fabricated for the 3.1 to 10.6 GHz band with notch behavior at 5.8 GHz. Additionally, an efficient technique is applied to this antenna for a further area reduction of 50%. The performance of this miniaturized antenna is compared with the main-size antenna. Using both...
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...
