Abstract

　ＲＦＩＤタグの配列順序とアンテナに対する移動方向を識別することができるリーダライタを提供する。このリーダライタ５０は、ＶＣＯ２の出力信号の位相を、基準となる入力信号の位相に同期させるＰＬＬ回路１と、ＰＬＬ回路１の制御電圧に基づいて所定の周波数を発振するＶＣＯ２と、ＶＣＯ２から発信された信号をマイクロ波に変調する変調器３と、マイクロ波の方向により向きを決定するサーキュレータ５と、マイクロ波を発信してタグ７からの反射波を受信するアンテナ６と、ｓｉｎ波を復調するミキサ９と、ｃｏｓ波を復調するミキサ１１と、ミキサ９の信号から所定の周波数成分のみを通過するＢＰＦ１２と、ミキサ１１の信号から所定の周波数成分のみを通過するＢＰＦ１３と、Ａ／Ｄコンバータ１４とＡ／Ｄコンバータ１６から位相を演算する演算器１５と、を備えて構成されている。
