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 3.45GHz. It achieves TX power of 10dBm with 18dB of power tuning. The pulse width is tunable between 46ps to 310ps and initial bistatic measurements distinguish 4 reflectors across a 6cm region signifying progress towards the development of a diagnostic medical imager in silicon.

90GHz脉冲发射机，近场/远场能量抵消，采用双环天线

利用近场/远场能量抵消的反射、双环、开关天线集成在90 GHz脉冲发射机(TX)中。TX具有高开/关比，良好的天线效率，PRF高达3.45GHz。它实现了10dBm的TX功率和18dB的功率调谐。脉冲宽度在46ps到310ps之间可调，最初的双基地测量在6厘米的区域内区分了4个反射器，这标志着硅诊断医学成像仪的发展取得了进展。
