摘要


本論文研究高效率電磁波照射系統對生物的影響,系統頻率設定為3GHz,發射端利用模組PLL鎖頻在頻率3GHz,訊號經過高轉換效率傳輸線CLASS-E功率放大器訊號放大以後,進入發射端高指向性2X2微帶陣列天線發射訊號,最後接收端為一個整流電路,並在負載上串上一個LED燈作為標誌提醒,當LED燈亮起時表示有接收到電磁波。  發射端使用PLL模組,利用MPLAB撰寫嵌入式C語言,燒錄至PIC控制PLL鎖頻在頻率3GHz。高轉換效率傳輸線CLASS-E功率放大器設計使用Agilent ADS 2009模擬做為實做電路架構與參考,將訊號放大。天線初步設計使用Ansoft HFSS 11設計與模擬高指向性2x2微帶陣列天線,作為實現天線的參考來源。整流電路初步設計使用Agilent ADS 2009模擬做為實做電路架構與參考,並將高頻訊號整流成直流電源。 經過數個月照射後發現所生出的後代其性別比例(男/女)是86%,並在動物實驗解剖血液分析以後發現變異,未來希望能將其運用到更多實驗上。

This thesis discuss about the biomedical affection of exposing to the radiation caused by high frequency electromagnetic system. System operating frequency is 3GHZ generate by using PLL module which generate stable frequency,signaling through the high conversion efficiency of microstrip line CLASS-E power amplifier. Signal amplification after entering the transmitter high directivity 2X2 microstrip array antenna. Finally, the receiving end of a rectifier circuit and the load connected to an LED light as a symbol to remind,when the LED lights that have received electromagnetic waves. Transmitter uses PLL module. In order to control the output frequency of PLL,we use micro poccessor to set the divisor of PLL locked frequency 3GHz by C code. High conversion efficiency of the transmission line CLASS-E power amplifier design using Agilent ADS 2009 as the reference to amplify the signal. We use Ansoft HFSS 11 to do the simulation for the high-directivity microstrip 2 x 2 antenna array, and as the reference of the practical receiving antenna.We use preliminary design of the rectifier circuit simulatedon Agilent ADS 2009 as the practical circuit, and high-frequency signal is rectified into DC power by this circuit. After several months of radiation,we found that the sex ratio of their offspring birth (male / female) was 86%,and blood analysis in animal experiments later discovered anatomical variation. We hope to apply it to more experiments in the future.
