摘要： A hand-held antenna system allows medical personnel to ascertain the presence or absence of objects (e.g., medical supplies) tagged with transponders in an environment in which medical procedures are performed. In use, the hand-held antenna system may be positioned proximate a patient at a time after a medical procedure, such as after childbirth, so the system can scan the patient's body to determine the presence of objects tagged with transponders. The antenna system includes two sets of three antenna elements arranged mutually orthogonal to each other to transmit and receive signals in at least three coordinate directions. A controller is coupled to the antenna elements to transmit signals to the transponders and to receive response signals. The antenna system may operate in a static scan mode wherein the antenna system is held in a fixed position by a user and a dynamic scan mode wherein the antenna system is moved by a user.

摘要翻译：手持天线系统允许医务人员在执行医疗程序的环境中确定标记有应答器的物体（例如，医疗用品）的存在或不存在。在使用中，手持式天线系统可以在诸如分娩之后的医疗过程之后的某个时间定位在患者身体附近，因此系统可以扫描患者的身体以确定标记有应答器的物体的存在。天线系统包括彼此相互正交布置的两组三个天线元件，以在至少三个坐标方向上发射和接收信号。控制器耦合到天线元件以将信号传送到应答器并且接收响应信号。天线系统可以以静态扫描模式操作，其中天线系统由用户保持在固定位置，并且其中天线系统被用户移动的动态扫描模式。
