    • A dynamically reconfigurable antenna system for an RFID (Radio Frequency Identification) reader/encoder includes a plurality of antenna elements; and a mechanism constructed and adapted to dynamically and selectively configure said plurality of antenna elements during operation thereof. The antenna elements may be arranged in a pattern of conductive areas, and each antenna element is switchably connectable to ground or to a transmission line connectable to the RFID reader/encoder. Each antenna element may be square, rectangle, circular, or diamond shaped. The antenna elements may located on an inner layer of the multi-layer printed circuit and wherein regions above the antenna elements are a dielectric layer or a slot aperture. The antenna system may be incorporated into an RFID encoder/reader.
    • 用于RFID(射频识别)读取器/编码器的动态可重构天线系统包括多个天线元件; 以及构造和适于在其操作期间动态地和选择性地配置所述多个天线元件的机构。 天线元件可以布置成导电区域的图案,并且每个天线元件可切换地连接到地或可连接到RFID读取器/编码器的传输线。 每个天线元件可以是正方形,矩形,圆形或菱形。 天线元件可以位于多层印刷电路的内层上,并且其中天线元件上方的区域是电介质层或槽孔。 天线系统可以结合到RFID编码器/读取器中。
