Abstract
This chapter covers the design and performance of a low-cost, compact UWB uniplanar antenna operating across the entire UWB of 3.1–10.6 GHz, which can be easily integrated with the designed CMOS UWB transmitter and receiver. Especially, various impulse time-domain measurements are conducted to demonstrate the performance and suitability of the designed UWB uniplanar antenna for transmitting and receiving impulse signals that contain all frequency components from 3.1 to 10.6 GHz, which are essential for UWB impulse systems. The UWB uniplanar antenna is further integrated with the previously developed CMOS tunable pulse generator to form the UWB transmit prototype. This UWB transmit prototype can transmit monocycle pulses with pulse duration tunable from 160–350 ps with the impulses supplied from the integrated pulse generator. The received pulses maintain good symmetry with no serious distortion and ringing. The UWB transmit prototype can also transmit signals having shape similar to the first derivative of the monocycle pulses provided by the integrated pulse generator. Both the impulse and monocycle-pulse transmission results clearly demonstrate the workability of the CMOS-based tunable UWB transmit prototype for UWB impulse systems.
