Keating & Bennett, LLP
Transceiver and radio frequency identification tag reader
In a transceiver, on a top surface of a rectangular plate-shaped substrate, transmission radiating elements and receiving radiating elements are provided. The transmission radiating elements extend in the horizontal or lateral direction from the center of the substrate. The receiving radiating elements extend in the vertical or longitudinal direction from the center of the substrate. Inductors included in a matching feeding element are individually electromagnetically coupled to transmission-side feeding points that are inner end portions of the transmission radiating elements and receiving-side feeding points that are inner end portions of the receiving radiating elements. A transmission signal is transmitted with a wave polarized in the horizontal or lateral direction, and a signal having a vertical or longitudinal polarization direction is received.
