  • Hand-held dual spherical antenna system
    Patent number: 9690963
    Abstract: 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.
