Abstract
An antenna that is used to read and/or write radio frequency identification tags is integrated into the structure of a door frame or other portal. The antenna may incorporate multiple radiating elements and frequency diversity to increase the reliability and accuracy of tag reads or writes, and to provide compatibility with a variety of RFID tags. The design of the antenna may also incorporate a Photonic Band Gap (PBG) antenna substrate.
Claims32
An antenna for communicating with an RFID transponder, the antenna comprising
- an antenna integrated into a portal, said portal substantially enclosing an opening.
A system for communicating with an RFID transponder, the system comprising:
