本文介绍了一种用于微波成像应用的带有片上天线的紧凑型 F 波段雷达传感器。前端芯片采用 0.13 μm SiGe:C 技术制造，具有 120~140 GHz 的宽带宽以及 0.633 mm2 和 0.689 mm2 的紧凑尺寸，并带有片上天线。片上天线针对小尺寸进行了优化，轮廓仅为 570μm x 250μm。片上天线的增益在 128 GHz 时介于 0 dBi 至 -3.3 dBi 之间。发射器和接收器的功耗分别为 175mW 和 205mW，距离分辨率为 1.5 cm。
This paper presents a compact F band radar sensor with on-chip antenna for microwave imaging applications. The frontend chips are fabricated in a 0.13 μm SiGe:C technology and feature a wide bandwidth from 120~140 GHz and a compact size of 0.633 mm2 and 0.689 mm2 with on-chip antenna. The on chip antenna is optimized for small size, with a profile of only 570μm by 250μm. The gain of the on-chip antenna is between 0 dBi to -3.3 dBi at 128 GHz. The transmitter and the receiver consume 175mW and 205mW respectively, and exhibit a range resolution of 1.5 cm.
