    摘要: A circularly polarized antenna includes a generally helical wire defining a generally cylindrical passage having a first end and a second end. A first ground plane is proximate the first end of the generally cylindrical passage and has a width substantially equal to a diameter of the generally cylindrical passage. A cable extends through the generally cylindrical passage and is electrically coupled to the first ground plane and to the generally helical wire proximate the first end.

    摘要: A radio frequency identification (RFID) tag is adapted to operate with a wideband or multiple band of frequencies, such as 860-960 MHz. The RFID tag includes a flexible antenna inlay structure that can be integrated into a rigid structure to form a rigid RFID tag. The antenna inlay structure can be folded to provide a compact rigid RFID tag. The antenna inlay structure may also be used in a smart label. The antenna inlay structure can work with RFID chips operating under Gen 2, ISO, or other protocol. The RFID tag can be provided with a metallized label that operates to shield the antenna inlay structure against electromagnetic effects of an object (such as a metallic object) having the RFID tag affixed thereon.
