Antenna for rear scatter-based passive or semi passive transponder of radio frequency identification system, has branch with section connected with another section, where thin layer of branch and integrated circuit are formed on substrate

摘要

The antenna (16) has two antenna branches extending outwards from a connection area and connected with an integrated receive circuit (17). A frame-like conductor path section is designed to connect the branches with each other. Each antenna branch has a u-shaped conductive path section that is connected with the connection area. Another u-shaped conductor path section of each branch runs parallel to the former path section and connected with the former path section. A thin conductive layer of the branch and integrated circuit are formed on a substrate.
