摘要

智能马桶的存在感检测、坐位检测、水位检测等受到了广泛关注。本文采用一种低成本、结构简单的24G毫米波雷达，一个发射器和两个接收器来实现这些功能。存在检测和座位检测要求天线向前辐射信号，而水位检测要求天线垂直向下向水面辐射信号。提出了一种新型的毫米波雷达双向辐射天线。发射天线是由维瓦尔第天线和宽带高效电磁结构(WHEMS)天线组成的端射与宽频辐射混合天线。混合火端辐射天线用于存在探测和座位探测，宽侧辐射天线用于水位探测。利用天线的优势，我们实现了对厕所使用者的精确跟踪，水位测量精度可达到±2mm。

Antenna Design of Millimeter Wave Radar for Smart Toilet

Presence detection, seating detection, and water level detection in smart toilets have received widespread attentions. This paper uses a low-cost, simple structured 24G millimeter-wave radar with one transmitter and two receivers to achieve these functions. Presence detection and seating detection require the antenna to radiate signals forward, while water level detection requires the antenna to radiate signals vertically down to the water surface. This paper proposes a new bidirectional radiating antenna of millimeter-wave radar. The transmitting antenna is a hybrid end-fire and broadside radiating antenna, composed of the Vivaldi antenna and the wideband high efficiency electromagnetic structure (WHEMS) antenna. The hybrid end-fire radiating antenna is used for presence detection and seating detection, and broadside radiating antenna is used for water level detection. With advantages of the antenna, we have achieved accurate tracking of toilet users, and the water level measurement accuracy can reach ±2 mm.
