Abstract :
Blind spots often occur in RFID system. This paper presents an enhanced RF receiving circuit design including four receiving channels and a circulator. The proposed design is simple, but it can eliminate blind spots and improve reading performance. Experimental results show that the proposed design improves the reading efficiency distinctly, and reduces the blind spots obviously compared to the conventional RFID reader design.
