碩士 === 國立臺灣科技大學 === 工業管理系 === 99 === The purpose of the thesis for the hottest tablet PC is to present a series of methods to reduce the influence of the electromagnetic waves to the human body。For example, why do we have to output maximum power ? How do we control output power ? And how do we extend the design from a cellphone to a tablet PC ? The design starts from to simulate the connection between the design of antenna and SAR by HFSS, and then I will propose the solutions of the proposal to analyze the advantages and disadvantages of each proposal。 Finally, I will use questionnaire survey to get the basis of the design, and to prove the design with the results of the tests。The design can provide reference for engineers like ID、ME、EE、RF、Antenna … The abstract as follows: To discussion of documents: According to the information of documents, to probe into the influence of the electromagnetic waves to the human body and the definition of the SAR. Also, to know well how all kinds of the communication systems to control the transmission power and found the transmission power level related to BS received uplink signal quality . The elements that influence SAR: According to the experience and practice of the cellphone design, to find out the relevances that are between the position and design of the antenna and SAR. We found if antenna location more farther from bady the SAR value will more lower. New solution: Compare the advantages and disadvantages of the current methods of the design, and bring up new solution of improvement by switch antenna to leave body. The analysis of Tablet: According to require of the new solution ,to design a questionnaire survey so as to get the basis of the antenna location to avoid user to touch . Testing: To carry out an experiment to prove the results of the new solution.
