Description
該第2アンテナは、該第1アンテナのスロット中に設置され、該絶縁隔離板片の上表面上を覆うループ回路導電箔膜アンテナであり、そのループ回路の両極端は、無線周波数識別RFIDチップに電気接続する。
装置標準設定値: ISO 18000-6C 、Query 、F: 25 us DSB-ASK 、R: 40 kbps FM0、2W EIRP
掃引間隔 : 800MHz 〜 1000MHz
試験方法: Tagをアルミ板に貼付した試験

Wake Up ウェイクアップ
1.該装置は、UHF RFIDのチップタグのみを測定できているので、測定結果からUHF RFIDのチップを、採用することを得ることができる。
2.上記論的読み取り範囲前方(Theoretical read range forward)試験からに、該タグ測定有効読み取り距離最大値が約13mであると分かる(ISO 18000-6C,UHF RFID 周波数規範860MHz〜960MHz)。
等価等方輻射電力(英語:equivalent isotropically radiated power,EIRP)、又は実効等方的放射電力(英語:effective isotropically radiated power,EIRP)と称するものは、無線電機通信分野の1つのよく見られる概念であり、それが指すのは、衛星又は地上局の某指定方向上の輻射電力である。理想の状態において、アンプ送信電力にアンテナの増幅を乗算したものに等しく、対数方式で計算する時、EIRP=PT +Ga -Lcと表すことができ、単位は、dBwであり、そのうち、PTは、アンプ送信電力を表し、Gaは、アンテナの増幅を表し、Lcは、フィーダの損失を表す。例えば、2W EIRP=500mW+8dbi-2 db lossである。
Transmitted Power: 送信電力
Theoretical read range forward: 理論上の読み取り前方距離
Theoretical read range reverse:異なる送信電力において、タグが起動された後逆向きに散乱し、リーダアンテナがタグを読み取る最遠距離として定義する。
Backscattered power ( dBm ) vs Transmitted power: 測定ユニットが送信電力の大きさを調整し、タグを起動した後、逆向きに測定ユニットに散乱し返す電力の大きさとして定義する。
Power on tag reverse: 異なる送信電力において、タグが起動された後の逆向きの散乱電力値として定義する。
