Abstract
【解決手段】誘電体基板1に2つのパッチ導体2A,2Bと接地導体3を形成した電波偏波変換共振反射器D1と無線ICタグ4とを組み合わせ、それら2つのパッチ導体の平面共振による効果によって無線ICタグ4のタグアンテナに流れる電流を強くすることで、小型で高感度の無線ICタグ装置を実現する。さらに、誘電体基板1の下面(実装面)に接地導体3を形成することにより、接地導体3側への電波(電界成分)の放射をなくし、金属で構成される物体や液体を収容する容器等であっても、無線ICタグ装置T1を実装できるようにする。

上記した実施形態1の無線ICタグ装置とその比較例の各性能を実験により評価した。ただし、実験には、2.4GHz帯RFIDシステムを用い、リーダの出力を2.45GHzで300mWとすとともに、リーダアンテナには、利得14dBiの円偏波アンテナを用いた。また、無線ICタグとして、ポリプロピレン誘電体基板上にダイポールアンテナ(タグアンテナ)を形成し、そのダイポールアンテナの中央部にタグICを実装した一般的な無線ICタグを用いた。
[比較例1−1]
まず、2.45GHzにおいて、上記した無線ICタグ単体の通信距離を、上記のリーダとリーダアンテナを用いて測定したところ、通信距離は88cmであった。
次に、図4の構造において、パッチ導体12Bを形成せずに、1つの円偏波用のパッチ導体12Aだけを形成して電波偏波変換共振反射器を構成し、そのパッチ導体12Aの上側に上記した無線ICタグを搭載して無線ICタグ装置を作製した。この無線ICタグ装置の通信距離を、上記のリーダとリーダアンテナを用いて測定したところ、通信距離は252cmに延長した。
図4の構造において、厚さ3mm厚の発泡誘電体基板を用い、その発泡誘電体基板の裏面に金属箔膜による接地導体を形成する一方、発泡誘電体基板の上面に、図4に示す円偏波用の2つのパッチ導体つまり略正方形で対角部に切欠C1を有するパッチ導体12A,12Bを近接した状態で形成して電波偏波変換共振反射器D11を作製した。なお、各パッチ導体12A,12Bの一辺を約53mmとし、それら2つのパッチ導体12A,12Bの間隔dを13mmとした。
上記した実施形態3の無線ICタグ装置とその比較例の各性能を実験により評価した。ただし、実験には、2.4GHz帯RFIDシステムを用い、リーダの出力を2.45GHzで300mWとすとともに、リーダアンテナには、利得14dBiの円偏波アンテナを用いた。また、無線ICタグとして、ダイポールアンテナ(タグアンテナ)にタグICを実装し、ポリプロピレン素材でケーシングしたものを用いた。無線ICタグの外形寸法は厚さ:4mm、長さ:74mm、幅:15mmとした。
[比較例2−1]
まず、2.45GHzにおいて、上記した無線ICタグ単体の通信距離を、上記のリーダとリーダアンテナを用いて測定したところ、通信距離は99cmであった。
図8及び図9の構造において、4mm厚さの発泡誘電体基板を用い、パッチ導体32として、一辺が53mmの略正方形であり、その略正方形の互いに対向する一対の角部(対角部)に切欠き(面取り)C1を設けたパッチ導体(図4参照)を形成して電波偏波変換共振反射器を構成し、その電波偏波変換共振反射器の誘電体基板31の空洞31cに、上記した無線ICタグを挿入配置して無線ICタグ装置を作製した。なお、最大の通信距離が得られるように無線ICタグの挿入位置を実験的に調整した。
