Abstract

In this paper, we propose a new near-field reader antenna for 900 MHz RFID. The proposed antenna consists the micro-strip antenna with the periodic structure. The overall dimension of the antenna is $313mm{\times}152mm{\times}14mm$. The antenna has the uniform E-field distribution in near field region and the heart-shaped radiation beam pattern (Peak gain=-2 dBi). The transmitted power range is from 17 dBm to 23 dBm. We focus on minimizing the detected error by suppressing the reflected power from the metal, which is attached to the surface by tag, and by reducing the transmitted power from tag.

본 논문에서는 근접 영역에 적용할 수 있는 새로운 900 MHz RFID 리더기 안테나에 대한 연구 결과를 제안한다. 본 논문에서 제안된 안테나는 주기성을 갖는 마이크로 스트립 안테나 구조를 사용하였다. 안테나의 크기는 $313mm{\times}152mm{\times}14mm$ 이다. 안테나의 성능은 근접영역에서 균일한 전계 분포를 갖고, 안테나의 이득은 -2 dBi 이고 하트 모양의 빔 패턴을 가진다. 제안된 안테나는 리더기의 송신출력이 17 dBm에서 23 dBm까지의 범위를 보인다. 본 논문에서 제안된 안테나는 금속면 위에 태그가 선적이 될 때 태그의 금속성분으로 인한 반사전력을 최소화하고 외부로 방사되는 전력을 최소화하여 오인식을 최소화하였다.
