ABSTRACT:
A radio frequency identification tag reading/writing station is adapted to be used with a radio frequency identification tag reader/writer in order to read/write radio frequency identification tags on a continuous web of carrier material. The radio frequency identification tag reading/writing station includes a first waveguide to coax adaptor, a second waveguide to coax adapter, and a window assembly having a window therein, the window being sized and shaped such that a tag on the web of carrier material under test is exposed to radio frequency read/write energy, but such that tags on the web of carrier material adjacent to the tag under test are shielded from the radio frequency read/write energy. The first waveguide to coax adapter and the second waveguide to coax adapter are disposed end-to-end with the window assembly being disposed therebetween.
