Description
以下、この発明の実施の形態を、図面を参照して説明する。図1はこの発明の実施の形態に係るRFIDタグシステム100の全体構成を示すブロック図である。RFIDタグシステム100は、RFIDリーダライタ10と、RFIDタグ50とを含む。RFIDリーダライタ10は、RFIDリーダライタ10全体を制御する制御部20と、制御部20に接続された送信部11および受信部12と、送信部11および受信部12に接続されたアンテナ13とを含む。
次に、この発明の第2実施の形態について説明する。上記実施の形態においては、図5(A)に示すように、RFIDタグ51は対向する一対の水平方向の辺と、対向する一対の垂直方向の辺とからなる矩形状のタグケース53aに、水平方向に延在するアンテナ52aを有するRFIDタグ51を斜めに傾斜して設けた(図2参照)。
次に、この発明の第3実施の形態について説明する。パレット等にRFIDタグを取付けて使用する場合、パレットは水平置きだけでなく、垂直置きにて使用される。RFIDタグが正確に45度傾斜してパレットに取付けられれば、いずれの場合においても対応可能であるが、実際はそうとは限らない。この場合、第1および第2実施の形態であれば、交信不良が生じて、単に、斜め偏波を用いただけでは、水平置き/垂直置き両方のパレットに対応することができない。例えば、パレットを水平置きしたときに、右斜め45度でタグを設置した場合、このパレットを立てた場合に左斜め45になってしまう。RFIDリーダライタの偏波面を水平置きに合わせて右斜め45度としていた場合は、RFIDタグとRFIDリーダライタでとの偏波面が合わなくなるので読み取れない。
Claims (1)
- RFIDタグとRFIDリーダライタとが通信するRFIDシステムであって、
前記RFIDリーダライタおよび前記RFIDタグは、それぞれが、
長手方向に延在する棒状のアンテナを有し、
前記それぞれのアンテナは、床や壁に対して傾斜し、且つ、それぞれのアンテナの傾斜が合うように設置され、前記床や壁に対して斜めに傾いた偏波面を持つ直線偏波の電波を送受信する、RFIDシステム。
