本論文建構高容量的無晶片式射頻辨識系統，將圖書館書籍的入藏號碼自動轉為無晶片式射頻辨識標籤，並以全波模擬驗證標籤的讀取可靠度。近年來，越來越多的研究關注無晶片式射頻辨識（chipless RFID），企圖利用移除晶片的標籤降低系統建置成本。然而，目前此技術仍在學術發展階段，此系統不僅尚未商品化，連通訊規格都尚未制定。本論文使用頻域編碼的方式，改變傳統的研究方法，不先去制定通訊頻段才設計諧振器；我們先分析37種諧振器的雷達截面積頻寬，從中決定最適合的結構，並指定通訊時單一頻率槽的頻寬。之後，藉由分析諧振器的金屬／槽孔寬度對頻寬的效應，我們決定通訊頻段的範圍。這些分析指出21位元圖書館管理的通訊頻段應設定為1.7–4.7 GHz，最適合的諧振器為半波長槽孔，而且每個標籤應放置7個諧振器。
有鑑於圖書館有多達三十五萬本館藏，入藏號碼必須能簡易、自動地轉為標籤結構，避免人為的逐一設計或軟體的反覆微調。本論文提出降低諧振器互耦合的標籤結構，發展一不需迭代的標籤自動成型技術，使每本書籍都能快速產生對應的無晶片式射頻辨識標籤。我們取樣37本書籍，分析標籤的讀取可靠度，發現37件書籍編號均能被正確讀取。我們也實做這些標籤，量測其雷達截面積響應。因此，本論文展示了高容量無晶片式射頻辨識的可行性。
