CORE ANTENNA FOR EAS AND RFID APPLICATIONS |
摘要 |
A core antenna system for use in electronic article surveillance (EAS) and radio frequency identification (RFID) systems. The core antenna system may include a core antenna. The core antenna may include a core, a first resonant winding disposed around at least a portion of the core, the first resonant winding having a first number of winding turns Nl, and a second non-resonant winding disposed around at least a portion of the core, the second non-resonant winding having a second number of winding turns N2, the second number of turns greater than or equal to the first number of turns. The core antenna may be mounted on a shield plate and tuned to an operating frequency on the shield plate such that when the shielded core antenna is further mounted on a mounting surface, e.g., of a checkstand, no significant de-tuning of the antenna takes lace. |
