本論文研究以433 MHz做為微波傳送功率頻段並以2.4 GHz通訊節點做為資料回傳,以建立一套完整微波充電系統,在於微波頻段選擇上,透過公式的推導,得到傳輸的最佳方案,而天線設計係採用Yagi-Uda天線之變形以節省面積。
此微波傳電系統包含一組發射端與一組接收端。各自皆有一個433MHz之Moxon antenna與耦合器。發射端另外含有一個高功率放大器,而接收端則含一個有RF-DC整流器。發射端的實際輸出功率可以藉由量測耦合器的輸出埠得知。同理,接收端的實際接收功率也可藉由量測接收端的耦合器得知。
為達到自動功率偵測之目的,本論文利用2.4 GHz之感測通訊節點來達成。當功率接收端接收到功率後,透過感測節點內建之類比-數位轉換器功能以檢測負載端電壓,並再利用無線通訊發射端回傳資料,且經由無線通訊接收終端之C#程式讀取資訊,藉此完成此研究。


The microwave power transmission system is used to wireless power transmission. In proposed wireless power transmission system, the data link band and communication band are located at 433 MHz and 2.4 GHz, respectively. The frequency band selection is suggested by Friis formula. For PCB area reduction, the modified Yagi-Uda antenna is proposed.
There are a transmitter and a receiver in proposed microwave power transmission system. Both TX and RX have a Moxon antenna and a coupler. Besides, a high output power amplifier and a RF- DC rectifier are included in transmitter and receiver, respectively. The real output power of transmitter and input power of receiver could be measured from output port of coupler.
For auto- power detection purpose, the 2.4 GHz sensor node is used in this work. When the RF power is received, the RF power will be detected by built-in ADC of 2.4 GHz sensor node. And this information will be transmitted to receiver of data- link system. Finally, this information will be processed by C# and presented on PC.
