一般來說，整流偵測天線標籤需要一組天線以及一組整流電路來構成，利用蕭特基二極體的整流效應將天線所接收到的訊號經過半波整流後可得到直流分量以及二倍頻諧波分量，利用二倍頻天線可將整流後得到的二倍頻訊號回傳至發射端天線，藉此達到偵測標籤所在位置的功能。另外直流的部分則可用來為所需的設備供電，可以額外對整流器進行設計以提供穩定的直流電壓，藉此可達成不需要電源即可運作的獵能標籤設計，本論文重點著重在天線陣列的開發與整合，直流輸出的部分將以概念與理論形式說明。
本論文為設計一可用來偵測2.4 GHz 訊號並且將接收到的訊號利用二極體電路轉換成二倍頻的 4.8 GHz 訊號以及直流分量的獵能標籤陣列。利用微帶天線的電流分布特性可以使用槽孔來分割出2.4 GHz 天線以及 4.8 GHz 天線，以達到最佳面積使用效率。主要研究部分著重在天線架構的提出以及天線陣列的開發。從單一天線模型的開發，擴展到1×2 天線陣列，再到2×2 天線陣列，詳細探討本論文之天線陣列的設計流程、量測實驗以及問題與討論。最後再將2×2 天線陣列與整流電路做整合，合併在一組印刷電路板上，完成本論文所提出的諧波標籤陣列系統。

In this thesis, a design of 2.4 GHz second harmonic detection tag for wireless energy harvesting was proposed. The overall research focuses on the development of merged 2.4 GHz and 4.8 GHz antenna arrays, used for receiving RF energy and
transmitting harmonic signal for the harmonic detection tag.
This thesis will be divided into two main parts. In the first part, we provid the
design of the antenna array and discussed the design and simulation results of single antenna, 1×2 antenna arrays, and 2×2 antenna arrays based on 1.6mm FR4 printed circuit board, followed by practical implementation and measurements. We
explored various issues encountered during the development process and validated the antenna array model through final measurements.
In the second part, we focused on the design and simulation of the rectifying circuit with the harmonic detection tag. We integrated the rectifying circuit with the proposed 2×2 antenna array and performed implementation, experiments, and measurements to complete the designed framework of the harmonic detection tag array presented in this thesis.
