Abstract

A reflective, dual-loop, switching antenna utilizing near-field/far-field energy cancellation is integrated in a 90 GHz pulsed transmitter (TX). The TX features high ON/OFF ratio, good antenna efficiency and PRF up to 3.45 GHz. It achieves TX power of 10 dBm with 18 dB of power tuning. The pulse width is tunable between 46 ps to 310 ps and initial bistatic measurements distinguish 4 reflectors across a 6 cm region signifying progress towards the development of a diagnostic medical imager in silicon.
